Hi krass,

re:
> The question is: is it possible to make folders in the list of objects?

Sorry not currently but it is high on my list of stuff to work on.


> Perhaps there is already such a plugin for MOI3D, but I don’t know about it?

Adding this involves a major restructuring of the internal MoI code both in the scene browser UI as well as in the selection code (for groups). So it's pretty far outside the scope of what a script can do.


> Is it possible to add a property for additional windows to the interface so that they can be transferred to 2 monitors? Thank you!!!

That's also something I would like to add in the future, but it's not at as high of a priority level though compared to hierarchy in the scene browser.


> ps. Is it possible to add the function "export dimension lines" when exporting to PDF or AI?
> Sometimes this is very important, but now the export takes place without them, only objects. It is sad ;((

Dimensions do export to PDF and AI formats in the final v4 release. If they are not exporting for you then probably you're using an older v4 beta release, either get the last one at https://moi3d.com/beta.htm or upgrade to the v4 final version.

Dimension export to PDF/AI was one of the last areas to be developed before the v4 final release.
