I'm testing 2.7 and - though probably the same in 2.6 but unnoticed - I found it to be a little disturbing there is no confirmation dialog when you delete files... Selecting them and then choosing 'delete' from the menu is enough to destroy the selected files.
And with the menu items being close together, an error is made easily; too easy if you ask me.
I would very much like a confirmation dialog; just to make sure no file is deleted unintentionally. As always, this could be made configurable for those die-hards that never ever make a mistake
