I wish you could do render presents. For all render settings. Render type. Sample, Resolution, Filetype, all the checkboxes.
For example. I have a specific setting for my final outout. PSD, transparent, .Clownpass,labelpass, 200samples etc.
Quite often I need to do test renders, or just render a fix. That render will just be in .PNG, without any labels etc.
I wish I could just toggle between 2 profiles doing this.
Both for speed but also to avoid mistakes then you don't need to change it manually.
The presets can be saved, but also locked. Could possibly be a local feature for a general personal render preset that is used for all your files but probably the best would to include it into the .bip file. or do both so you never need to redo it.
+ extra wish
Make studios, multi selectable so you can multi delete.
