i'm impressed with lbc (and i'm a registered user of true launch bar). it still has a way to go but it shows promise and it it better on resources. my only request is that i be able to bring up a toolbar by hotkey and be able to navigate it by keyboard. i also see that you plan on adding folder support which is *great*. i would just like to comment that the folder node needs two options:
1) a node that shows the contents of a folder
2) add folder contents to this node
this offers significantly more flexibility and also allows users to combine the contents of multiple folders into a single node (which is great for AllUsers/DefaultUser/LoginName folders like quick launch, favorites, and start menu). it would also be useful for combining multiple playlist folders.
regardless, it looks great so far!
