Go to drag a bookmark into a toolbar folder (or onto the toolbar itself), and Orion will bog down, put up a spinning beachball, blank the toolbar, hang, and think about it for awhile before eventually coming to its senses.
Safari, given the same task, asks what I'd like the bookmark to be called (this is a really nice touch; Orion should copy) and then just instantly does it with no fuss, no delay, no hang, no beachball. The machine has an enormous amount of RAM, so it's not a hardware constraint.
Orion on the left, Safari on the right:
Orion should behave just like Safari on both counts: ask what I want to call the bookmark, and then create/add the bookmark quickly.
