Extended File Manager Functions

[marcnotenboom]

I print eyewear and have hundreds of combinations. Different sizes of fronts and temples and a lot of angles and curves. This makes up a lot of generated STLs. I would like to organize them better in stead of scrolling through the enormous list. Grouping is limited now. I cannot add a new STL to an existing group. And I cannot export an item from the tempel group together with an item from the rim group. It would be so great if it could work like a normal file manager. Also I cannot deselect all items viewed at once. Ik have to deselect all one by one.
