When viewing issues, child issues sometimes show up next to their parent issues. However if sorting by date this doesn't happen. it would be useful if the child issue was visually indented and stayed visible regardless of filtering.

Simple functionality:
Simple functionality would be to add a field on the view issues page showing the child # count of child bugs, clicking the # would link to that page so I could see the child issues from there.

An Additional Enhancement would be:
So something like, a +/- icon the user can click to toggle an issue's parent list, this would visually signify there are issues "under" this parent issue, and I can sort parent issues, and then drill down.
( basically same as above but avoids a reload )
