Thanks.
In the mean time I have fixed a number of bugs and implemented some TODO features:
- Fill Tags from filename sometimes ignores some fields
- Fill tags changes are ignored
- Quick button for filling tags doesn't work or sometimes ignore changes
- Tags changes are not reflected in the tag fields
- Implemented propagating of re-tagging changes back to main form
- Implemented multiple artist selection
- Implemented changing the case on tags: all caps, first letter on each word, first letter on first word
The changes involve some refactoring of the code which allowed to remove many repetitive code on the re-tagging side, and I'm still trying to figure out how to make it reusable and easy to read.
What I would like now is to add a tab for browsing the database in "virtual filesystem" because sometimes files are already orderer and tagging of such files would become easier.
