I think it would be really handy to be able to edit a preset and not be obliged to create a new one from scratch, even when all you need is to just slightly change a single aspect/parameter.
This would also be useful when you want to create a new preset which just slightly differs from an existing one.
Currently - unless I've been missing something - if you need to modify something you have to create a new preset from scratch, save it, then delete the previous one.
I also noticed that the Profiler allows saving a preset with a name which already exists... And this makes things even more compicated.
What do you guys think?
