Items 1–12 of the interface review: - Larger UI font (UI_FONT_SIZE) across widgets, menus, dialogs, Treeview rows. - DRK-red header bar; window title shows entry count; runtime-drawn red-cross icon (also written to data/icon.png for the launcher). - Status bar colour-coded by severity; transient messages auto-clear after 8 s, queue-count messages stay. - Tab 1: more form spacing, digits-only PLZ, explicit "Auswahl entfernen" + Delete key for queue rows, confirm on "Warteschlange leeren", modal on duplicate save. - Tab 2: raw lat/lon columns replaced by one "Karte" column (checkmark / red "fehlt"); ▲/▼ arrow on the active sort column; hint line always shows the saved-entry count. - "Karte öffnen" with no coordinates shows a dialog, not just a status line. - Window size/position remembered between sessions (data/window.json). Verified by building and driving the window under Homebrew Python 3.12 / Tk 9; non-GUI smoke tests still pass. Docs updated (changelog, overview, improvements, data-model, setup, dev-notes).

# Overview – what the app does
|
||
|
||
The app is a single window: a **DRK-red header bar**, two tabs, and a
|
||
**colour-coded status bar** at the bottom (grey = neutral, green = success,
|
||
orange = warning, red = error; transient messages fade back to neutral after
|
||
~8 s). The window title shows the total entry count, and the window remembers
|
||
its size and position between sessions (`data/window.json`). The UI font is
|
||
enlarged for readability (`UI_FONT_SIZE`).
|
||
|
||
## Tab 1 – "Neuer Eintrag" (new entry)
|
||
|
||
Workflow: build up a **queue** of entries, let them geocode in the background,
|
||
then save the whole batch at once.
|
||
|
||
1. **Entry form** – date (a **calendar picker**, `ttkbootstrap.DateEntry`,
|
||
pre-filled with today; typed input is accepted in `JJJJ-MM-TT` or
|
||
`TT.MM.JJJJ` and **validated** – an invalid date is rejected with a dialog),
|
||
city (autocomplete combobox), postal code (optional). Pressing `Return` in any
|
||
field, or the **+ Hinzufügen** button, adds the row to the queue.
|
||
The PLZ field only accepts digits.
|
||
2. **Queue table** – shows date, city, PLZ, and a live coordinate column that
|
||
updates from `⏳ wird gesucht…` to either `lat / lon` or `⚠ nicht gefunden`
|
||
as the background geocoder works through the queue.
|
||
- Select a row and press <kbd>Delete</kbd>, use the **"Auswahl entfernen"**
|
||
button, or click the `✕` cell.
|
||
- Right-click a row for *Löschen* / *Koordinaten erneut suchen*.
|
||
3. **Action bar**
|
||
- **Alle speichern** – appends every queued row to `orte.csv`. If any row
|
||
looks like a duplicate (same date + city + PLZ), a **modal** lists them and
|
||
asks whether to save anyway.
|
||
- **Warteschlange leeren** – discards the queue (asks for confirmation).
|
||
- **Karte öffnen** – regenerates `karte.html` and opens it in the browser.
|
||
|
||
## Tab 2 – "Einträge verwalten" (manage entries)
|
||
|
||
A table view of everything in `orte.csv`.
|
||
|
||
- **Columns:** Datum, Ort, PLZ, and **Karte** – a status column showing `✓` when
|
||
the row has coordinates or a red `fehlt` when it doesn't (the whole row is red
|
||
too). The raw lat/lon numbers live in the edit dialog, not this table.
|
||
- **Search box** – live filter across date, city, and PLZ (substring match).
|
||
- **Sortable columns** – click a header to sort; clicking again reverses. The
|
||
active column shows a ▲/▼ arrow. Default sort is by date, newest first.
|
||
Sorting by **Karte** groups the rows without coordinates together.
|
||
- **"Nur ohne Koordinaten"** toggle – filters to entries that have no
|
||
coordinates yet. The hint line always shows the total count, plus how many are
|
||
missing coordinates.
|
||
- **Edit** – double-click a row (or *Bearbeiten*) opens a modal dialog to change
|
||
date (calendar picker, validated) / city / PLZ. Two ways to fix coordinates:
|
||
a "Koordinaten automatisch neu suchen" toggle re-runs geocoding after saving,
|
||
or the **Breitengrad / Längengrad** fields let you type them in by hand
|
||
(both empty = no map marker).
|
||
- **Right-click → Koordinaten suchen** – runs geocoding for that one row
|
||
(handy for rows that failed the first time).
|
||
- **Delete** – *Löschen* removes the selected row(s) after a confirmation
|
||
dialog. This is **irreversible**, but a timestamped copy of the file is
|
||
written to `data/backups/` before every change (see
|
||
[data-model.md](data-model.md#backups)).
|
||
- **Karte öffnen** – same as on Tab 1.
|
||
|
||
## The map (`karte.html`)
|
||
|
||
Generated by `generate_map()`:
|
||
|
||
- Base layer: `CartoDB positron`, initial view centred on `[49.0, 9.0]`,
|
||
zoom 8 (roughly Baden-Württemberg).
|
||
- One **`CircleMarker`** per unique `(city, lat, lon)` group. Radius scales
|
||
linearly with the visit count for that location
|
||
(`5 + count / max_count * 20` px), colour is DRK red (`#CC0000`).
|
||
- Popup shows the city and the visit count; tooltip shows the city.
|
||
- Rows with missing/blank coordinates are silently excluded.
|
||
- If there are no usable coordinates at all, a dialog says so (and the status
|
||
bar shows a warning).
|
||
|
||
> The generated HTML pulls Leaflet, jQuery and Bootstrap from CDNs, so the map
|
||
> needs an internet connection to render even though the data is local.
|
||
|
||
## Geocoding behaviour
|
||
|
||
`geocode_city(city, postal_code)` tries a series of queries in order and returns
|
||
the first hit:
|
||
|
||
1. `"<PLZ> <city>, Germany"` (only if a PLZ was given)
|
||
2. `"<city>, Baden-Württemberg, Germany"`
|
||
3. `"<city>, Hessen, Germany"`
|
||
4. `"<city>, Germany"`
|
||
|
||
The regional bias is the `GEOCODE_REGIONS` constant (`Baden-Württemberg`,
|
||
`Hessen`) near the top of `app.py`. Results are rounded to five decimal places.
|
||
Nominatim's usage policy (max 1 req/s, identifying `user_agent`) is respected by
|
||
a manual `time.sleep(1)` in the worker loop.
|
||
|
||
If the geocoding service is unreachable (no internet), entries still save –
|
||
without coordinates – and after a few consecutive failures a one-time dialog
|
||
explains that the coordinates can be added later via *Bearbeiten*. The worker
|
||
thread logs failures to `data/app.log` and keeps running.
