The one where a wrong rename is no longer permanent.
You right-click, hit save, and a fraction of a second later realize the template was wrong. In 1.3, that's a single tap: the popup surfaces an Undo button on the latest rename that restores the original filename and quietly skips it next time.
We also mapped two keyboard shortcuts (toggle + open popup), added a real context-menu entry for one-off saves, and taught Renma to read image dimensions so your filenames can carry {width}, {height} and {dimensions} tokens.
- Undo the last rename in one click
- Keyboard shortcuts + context menu
- New {width}, {height}, {dimensions} tokens
