[ENHANCEMENT] Have a better default for the Save As composite option. (Added in IM 2021.3)
Have save as default to not save a full composite image in the project file. The composite is just a lot of wasted disk space if you do not turn the composite off. At the default 8-bit this is 72MB for a 24MP image.
I submit that this current default is not the normal case for Imerge projects. I believe typical Imerge projects, be it a simple photo or a complex composite, are stand alone images and not destined for use in Hitfilm (or other FxHome codebase apps).
