I find myself updating my custom compile format often. This requires choosing “Manage Compile Format Presets” from the “Format As” menu and then choosing “Update”. I’d rather see an “Update” button next to the currently selected item. Naturally, with a confirmation to clue the user in about what the button will do and the option to cancel.
The problem is that once you change your compile settings, it is no longer tied back to the original preset you started with, and becomes “Custom”, so at that point we would have no idea which preset should be updated. That’s why you have to go in and tell the software what you want.
