there are some suggestions, maybe you find it fine
1) "highlight matched brackeds": only when cursor is on "(" or ")" Don't hightight when cursor is inside brackets.
(like in "notepad++" on sourceforge)
2) add hotkeys:
"set/clear bookmark"
"next bookmark"
"previous bookmark"
(like in "notepad++" on sourceforge or coderush for delphi 5)
About 1, there's an option in 'CnPack'->'IDE Enhancements Settings'->'Source Highlight Enhancements' Dialog. A Checkbox 'Only Highlight when Cursor is between Brackets'.
About 2, We can consider this. We're trying to find a good way to configure hotkeys, not only those related to bookmark.
