It would be very nice is a subset of the regular "Find Usages" options could
work for Ctrl-Alt-F7.
The most valuable for me would be:
-Show import statements (Ctrl-I)
-Merge usages from the same file (Ctrl-F)
-Group by file structure (Ctrl-M) (see IDEA-13962)
I'm not asking about any buttons or anything in the Ctrl-Alt-F7 interface.
Instead, these shortcuts from the regular "Find Usages" could be supported
when the Ctrl-Alt-F7 popup is active.
The "toggle state" of any individual option would be persisted across Ctrl-Alt-F7
invokations, similar to how regular "Find Usages" works.
Ctrl-I would allow filtering out imports, which are (usually) not interesting,
and only fill space in the popup list.
Ctrl-F would allow grouping by file, which also can drastically reduce the
number of popup list items when only the containing file is relevant.
Ctrl-M would allow quickly understanding the context ("in which method?")
of a particular usage.
If those were available, I would expect Ctrl-Alt-F7 to actually fulfill 90%
of my "Find Usage" needs, relegating the regular "Find Usages" to the 10%
of "heavy" code queries.
