"edit" doesn't tell you if you already have said file open

Hello.
Noticed today the following behavior:
open a winscp connection to somewhere,
right click on a file, choose "edit"
now minimize the edit window.
now right click on the same file, choose "edit"

what I would expect to see: it would either "restore" the previously open edit file, or have a prompt saying "this file is already open by you!"

what happens instead: it seems to do "nothing"

feature request: handle this condition more gracefully somehow.

Cheers!
