Eric,
Care to share your org-evil mappings?
One 'conflict' which bites me every time is this:
I hit /blabla to locate a heading directly under which I want to insert a text line.
I then hit enter to acknowledge the find.
The display shows the heading line followed by its body lines (which all start with a hyphen)
I then hit o to insert a line directly under the heading and before the first existing detail line.
The result is however that the heading body closes, and that a line is added before the next header line, so under all existing detail lines of this header line.
This undesired behavior only happens if the heading was closed at the time of the find. If the find locates an open heading, hitting enter and than o behaves as expected.
