It's very dificult to change any Cover Photo in the app.
For example, if I need to re-fresh 2. picture from 3 existed in a song and I copy-paste new version from system into app, anytime this picture is new next cover with default position as last and as Front Cover, what is duplicating existed Front Cover in almost all situation.
Will be better if app will ask during copy-paste, if I wish to paste new cover or I wish to re-change one of existed covers. Does it sound fine?
The problem is very practical.
I have 10k pictures to change, because Sony A series of Hi-Fi players needs a baseline saved JPG as Front Cover, if you use progressive file (typical saving form for internet), Sony does not recognize a cover photo.
So, we must remember also, that Front Cover must be saved on 1. position for MP3 and last for FLAC or will be wrong recognized by players and Win.
If will be available in mp3Tag app a switch in Settings to change default behaviour of app during copy-paste the pic, will be so nice and usable.
For now new picture is always putted on last position between covers, it's fine for FLACs, it's wrong for MP3, so why after putting new Front Cover photo I have to manually move via copy-paste rest of covers saved in the file. Horror!
