I can't find the option you are mentioning

Ended up empty handed after looking thoroughly on both UCP and ACP.
Besides, its a bit extrange that in order to be able to edit tables I can only use simple view. If by default when I press edit, it inmediatly shows me de code (including tables) then It's what I'm looking for, else don't know what to do.
Just one aclaration, is it vbulletins fault or is it due to this hack that the tables get lost after pressing "switch editor mode"? (I doubt is due to this hack but still it is a valid question, I think.)
Thanks for helping mihai11
