Description
For the moment, when GUI saves project (in autosave mode, or because of ctrl-s pressed), saving is done in a main GUI thread.
For project with several large images open, and on weak laptops, it leads for unresponsiveness during seconds.
Within this item
- Modify saving algorithm, so it do not re-save already existing images on disk.
- Make saving done in separate thread.
Think how to save model, while there are changes ongoing
But as a first approach, make saving of heavy data (images) in separate thread, while saving a model still in a main thread.
- Provide status string "Saving..." somewhere.
The button status bar is a good place, but on some views it is already occupied by buttons.
