I’m always annoyed when i want to clear my bin to have it clean and fresh because i have to first select one item to then be able to click select all and then delete all items.
I think it would be a good idea to add a button to clear the bin like you can clear the history.
I think an alternative to a similar functionality would be to have the select all button visible before selecting a single item so you could directly select all and then delete.
It is not something huge with a big impact but i think this is one of the little things that can make anytype feel even more smooth with a good flow and good user experience.
