Quote:No and yes... In fact, it is not restricted to non-subfile elements. You can still select subfile elements "to group", but then you'll group only a copy of the element, since LDPE is not allowed to modify the contents of a subfile directly (that would be a way to complicated).Got it! it does group subfile+lines+quads. Note to self: subfile != subfile elements...
Otherwise, seems that the context menu "open in text editor" does nothing?
