Developer profiles

[haraldthi]

I need to grade (develop) several photos to the same standard, but run into a few problems.
The right way to do this for me, would mean being able to overwrite the profile I have laid on all the pictures, and have all the pictures loaded with said profile update automatically. Instead, Affinity Photo rejects saving a profile with a previously used name, so when updating the profile I need to give it a new name, and then change all the photos to use that new profile. Which is both tedious and messy.
I understand the need to protect users agains sudden and unwanted changes, but it goes too far. It slows down a whole class of use cases.
I also see it could be kind of slow to update a large number of pictures at once, but the advanced thing to do here would be a "lazy" approach, where the changes wouldn't be applied to the pictures before needed. As in viewed, saved, exported and so on. (But for me, either way is an improvement.)

I also tried the snapshots in the develop persona, and while I see that they have a limited use they are impossible to rename. Which makes it difficult to remember where I was when I took that snapshot.

Fix, please?
