Michael, that is very clever to set it in this way.
I mean if program detects "appdata" folder in MoI root it will putt settings from it.
And seems very easy to transfer all customizations to later versions.

Good job.

I also have one question.
How can we edit the icons we see in icon bar at the bottom of the program?
I have there 2 icons "Scripts".
One has stuff from custom UI + ones I copied to commands folder under appdata and other has also stuff from commands folder but it looks same as in my MoIv3.
I think I saw the post somewhere but probably putting wrong keywords into search.

Regards,
Juraj
