Standard IDE appendices "fasm" very simple. It is good, but in it there is no tool of a fast jump. I imagine it in the form of a vertical window at the left the screen. In it exist four lists — all procedures, all labels, all macroes and tempory (in current session) bookmarks. Four lists are switched as tabs. I think, it even will be easier and more beautiful, than spoilers/snippets a-la [+] ([–]). Thanks.

The IDE I am working on will have this, but I am not releasing it soon - maybe in a few months.
