In RoadMatcher we created something we called an Issues List. The idea
was that you could either select a feature or draw a box around an area,
and then mark it as an issue (with a state, title, comment, datestamp,
etc). Issues were actually just a special named layer. We had a modeless
dialog which looked like the Attribute View to let you zoom to issues,
sort them, mark them as done, etc.)

Fancier and less general than the Bookmarks idea. Bookmarks sound like a
great idea.

What is the scope of Bookmarks? Local to a single Task Frame (um - OJ
Project Frame?) The entire OJ instance? Would they be persisted and if
so how?

I quite liked the pattern of exposing things like this as a layer in the
Layer List (e.g the way the Fence works). Then users can use any
relevant tools directly on that layer. Basically then Bookmarks would
just be a special tool to create a Bookmark layer feature, and perhaps
(probably?) a UI dialog to allow friendly navigation around bookmarks
(although even this might not be needed - the Attribute View could serve
just as well for this.
