Forum Moderators: not2easy
I have read a post somewhere here on this topic but I haven't been able to find it. I'll post back with a link if I can come across it.
As far as usability is concerned, I wouldn't try to suppress that little annoying outline. Sure, it can mildly mess up the look of some pages, but folks are used to seeing it. If you take it away, you're risking losing some ease-of-use for some visitors.
