Thanks, This is very useful

thank you can you make history page and extension page

Has a clean layout like Chrome's bookmark manager but very slow responsiveness. Almost unusable with folders that have thousands of bookmarks.

Minimalista, limpio y efectivo. Recomiendo.

Nice look and feel - it would be nice if the icon would match to the current Firefox style (light and dark mode) and if I could select a specific folder which opens initially

It really needs the ability to mouse scroll wheel while dragging, and some UX color changes so its easier to see when youre selecting and such (in dark mode at least).
There is also issues with it getting the icons of the actual bookmarks or updating it properly which makes readability a bit worse than I wouldve liked.

Please make it remember the last opened folder on launch! Great otherwise.

Sometimes simplicity is under rated! Works great, real simple. No bloat no bs.. great job!
