If I have understood correctly the Events time line is based on EXIF Creation Date.
When scanning photos o dia the date is usally today, inserting the photos in a wrong sequence.
For this reason it would be nice to have the possibility to manually edit the Creation date of a single photo or if better of a batch of photos.
The editing could be added to tonfotos.ini file from photo editing page, putting the āEdit Creation Date Ctrl-Dā under āEdit Commentā menu.
