Feature request - Import/Export grouping lists

[speaker-60]

Hi thought about a feature to export and also import morph groups so we never loose them
I use daz3d and use a blender addon - https://bitbucket.org/Diffeomorphic/workspace/projects/DIF
Iv suggested the idea he gets imported morphs to be placed into your morph menu as he has his own atm so we can take advantage of your ordering/grouping system. Inside Daz there are often many morphs all sorted like this

I created this list as i moved and reordered all my morphs in daz, so the goal is to be able to replicate this into blender

In daz we can run user made scripts to i was thinking that we run a script to output a .json file that is a sort of atlas for this list of folders and where morphs are stored(morph names or there file names ect), the idea would be i import the morphs using Diffeomorphic which dumps the morphs into your menu loose, I run the scrip in daz to output the json then i go to your keyshape menu and 'Import' the json. This then moves all the morphs into there correct folders/categories making a perfect replication of the daz ordering system

This would still serve as a great feature beyond using it for daz as it would allow people to move this organization between blends for any model not just used with daz ect

As a side request, daz has types of morphs that are not shapekeys there more like bone morphs, these obviously wouldnt appear in the shapekey menu normally as there not technically shapekeys. Is there any chance you could add some sort of support for this or show how we can 'force' sliders into your menu so when importing the daz morphs all of them will show in your menu even if there bone morphs.

For universal use these essentially would be 'dummy' morph, in daz there are often morphs sliders that are driven to control other morph sliders like for example one slider controls two sliders for left and right so you can use the left and right sliders individually or use the 'both' slider that control the left and right together. Blender dosnt currently have this so adding a 'dummy' we can use to control multiple sliders would be great and again would be good to have regardless of using with daz

Also i didn't want to make a separate post for this, could you add a collapse/expand to the top menu so we can collapse it when we are not using it, would look cleaner Thanks :)

Edit: I just discovered this which i didnt actually know https://blenderartists.org/t/how-do-you-put-two-shape-keys-in-one-slider/555992/4 Could you allow us to show custom properties as sliders in your menu this would allow us to use them as multi morph sliders
