Since I urgently need the feature requested in feature request "Change previous days - ID: 2812242", I added the feature myself.
Rough concept:
- add new boolean setting "allowEditPast"
- when saving plan, not only the last two weeks are saved, but saving is started on week that contained the latest change
- show "Add" button on previous days
- allow "move time" on all days
- "touch" a day (i.e. set "modified" flag) when time was moved between two of its tasks
Open question:
I'm using rachota since two months, so I have no performance issues with this new feature. If you have data for lots of days, it may take some time to find the first modified day.
Open issue:
Unfortunately, since I use Eclipse instead of Netbeans, I was not able to add a dialog to simply add time to a task without transferring time from some other task (feature request ID: 2139518).
