Add a menu item that allows to reopen last used files/folders.
Do you mean something like this?
No, not really. I mean a menu item in File like “Open recent items:” and then a list of recent files and folders to open.
I agree, this would be useful. The current “Reopen last item” doesn’t seem to work when the last item was a project (folder), not just a single file, and if you work on multiple projects then it is far more useful to have a “Open recent items” list of the last X items/projects you opened. I’d suggest X be 5 or 10.
