When working on large scores I always miss having the possibility of a modeless bookmarks/menu window to navigate quickly between different areas of a score.
I started a thread on the (old) forum about this a long time ago, without results. I had originally also corresponded with Jari Williams if he could perhaps create such a plug-in, but it never happened.
It should really be part of Finale's own bookmarks feature, which, in general, is actually quite good and flexible, but this would be a great improvement.
I think it would be very useful for many users, if it were available. One frequent forum participant/moderator/expert (Peter Thomsen) said this: "I could not agree more. I would love to have the option of pulling off the sub-menu Bookmarks as a palette with clickable bookmarks."
