If it would be easier for a standalone program, look at the Reallusion downloader for their character creation platforms. This could either be a standalone program that could be made or maybe the Blender developers can add it to the next Blender version with a drop-down menu. Not to mention, Blender will keep updating to new versions which can take up some space overtime.
Some people just say, “Heck with the new version and continue to use the same version longer than they should.” or some people just say, “I need the latest feature of Blender to fully function.” while waiting to do projects on the new build of Blender. So, when a new blender version comes out, the user does not have to get on the site and download the whole blender software AGAIN. The implementation is an auto-updater for blender builds.
BLENDER DEVELOPERS, PLEASE READ!!! I really do not know where to post this but, I have a helpful implementation that Blender users would love.
