In Micro$oft Outlook when you click on the "attach" or "join" button, you can easily access to the recents files. And in the fork "Betterbird", it's seems there is a "recent" button from the version 91 : https://github.com/Betterbird/thunderbird-patches/blob/main/91/features/09-feature-attach-recent.pat...
Could you add this function ? First on Window$, and why not on Linux and macOS.
Thank you.
