When I tried to deactivate my style (in a popup window), I accidentally clicked on delete style. There is no confirmation for deleting! So I deleted my style which I was working on for a long time, and I have no backup! :(
Please, do confirmation for deleting, or move delete button somewhere else (why no to make a little cross in corner), so you can't click on it unintentionally.
I know it's my fault, and from now I definitely won't forget to do a backup, but please do some indulgence for inattentive people like me:).
(sorry if my english isn't perfect.)
