I’m using delete all the time in the identification module. Maybe i am just prone to error!
Like @Star3 , I use it when I add an ID then realise I can go to a finer rank… or should be coarser in fact…or remember the name of the subject in question - when its noted just moments later, I don’t see much point in leaving the original ID either, …I also feel its a bit unnecessarily messy…
For me, I would rather delete was a hotkey even so this could be quicker…as its painfully slow to do something so basic at present… ( this is mentioned on this older feature request though…so maybe in pipeline(?) )
