Thanks for the answer Oliver, I guess I probably won't be able to remember those subtilities and a generic end date criteria (and/or failed on date and/or applied on date) is then really missing.
Something else I really don't know where to write it but it feels really important in my way of using MB before NGS :
Let's say I click a user's edits, I see all his/her edits or her open edits.
I then used to begin to filter down the edits to progressively only see the wanted edits.
It is now impossible to begin filtering edits starting from a generic edit search page (entity/mbid/[open_]edits). ← the solution to this would be that clicking user/bob/edits/open would redirect to the appropriate complete detailed search URL (it was how it was done before) and same for /entity/mbid/open_edits → complete search URL ...
with this goold old Advanced edit search button that was opening the edit search tweaking page with current criterias.
PS. Notice the inconsistency between /user/bob/edits/open and /entity/mbid/open_edits
(really sorry for all this spam)
The five still open sub-tasks are now all under review.
