There are a couple sites I check obsessively. Is there a way to turn a bookmark into a button to show up on the menu for one-press access to the site?

if you mean on the menu itself the answer is no, if you want them on the bookmark pager that can be done. You can also have them on the BB Home screen. There is a third party app that takes URL and turns them into buttons on your homescreen.

Yeah...I think that's what I'm looking for. Would you happen to remember the name of this app? Thanks a ton.
