Thanks for the heads up. Actually I once had an idea for text tiddlers in that direction. It went like this:
- save a backup-tiddler every X characters entered/deleted (automagically in the background, using a counter appendix or prefix to the title)
- show a back-button that loads the last backup tiddler (discarding the open tiddler, no option to regret going back)
- discard all backups when the tiddler is saved
- allow users to define intervals (X and max. numbers of steps/backup tiddlers)
I never built this because I was not able to save and keep the tiddler in edit mode AND keep the cursor position, which would be mandatory for a useful solution. Reacently I read in another thread, that @saqimtiaz found a way to do it.
Maybe something similar would be possible for the image editor? I don’t know.
Kind regards, Thomas
