[Requests and ideas] The "Changes" panel lacks several basic features

**Mood:** 😔
**Category:** Requests and ideas

The "Changes" panel lacks basic features, e.g.:
- Can't open a file in editor by double-clicking on it from the files tree
- Can't right-click on a file in the tree to do actions (e.g. open the parent folder in Explorer)
- Double-clicking on a word in the git diff viewer doesn't select the word (it does nothing)
- The options for the tree are only "Committed", "Uncommitted", and "Last", it's missing "All" to just see the whole current state, which is the most useful thing while iterating.

Beginne damit, das Changes panel, seinen Dateibaum und seinen Diff-Viewer zu lokalisieren; im Issue werden keine Datei- oder Testpfade genannt. Behandle die aufgeführten Interaktionen und die fehlende “All”-Ansicht als separate Abnahmekriterien und bestätige das beabsichtigte Verhalten vor dem Coden.
