I’d like to suggest the addition of some sort of part list inside PreForm that can be selected and edited, which would make it easier to locate or select parts, as well as the ability to select and edit multiple parts at the same time.
In several instances I’ve had to manage many separate parts in one .form file. Managing these files can be a pain, especially since I can’t select multiples at the same time to edit, and sometimes parts can ‘disappear’ inside others or off the build platform area for some reason or another (this is probably a bug).
