Hi Could we get a tool to lock folders in Thunderbird ? Or a warning before moving folders with drag and drop. Pretty much what https://addons.thunderbird.net/en-us/thunderbird/addon/disable-draganddrop-tb-v2/ is probably doing - I'm just a bit worried to use addons that requires a permission: "Have full, unrestricted access to Thunderbird, and your computer" I think this would be a welcome addition to many, especially those whom use IMAP like Gmail to use their mail account. If you accidentally drag a folder into another it can result a huge mess. At the very least there should be an optional feature to get a warning message "Are you sure you wish to move this folder ..." Thank you so much for this awesome software. I've used Firefox probably a few decades already .. and now Thunderbird too. Love it!
