Argh I do NOT believe this!

I really should try to get some rest. I just removed all my sidebar buttons in one click. I was attempting to remove a button which had stopped working for some unknown reason and was going to return to the original page to retrieve it again. I then stumbled over my own fingers and removed the entirety of my buttons. NOW to go in search of all those buttons I so love to use and which live on my sidebar. There was no way to undo. argh blogger.
