First of all, thank you for your great tool and the export add on to blender! It's really exciting and pushes our imagination even further.

Here's a little suggestion: when we make a complex scene with a lot of parts, masking groups of parts is very important and thanks to this, editing is fluid and the Mecabrick tool does it very well! But, when we export our project to Blender, everything is in the same collection, and the editing work becomes heavier. Is it possible that the Mecabrick groups end up in separate collections in Blender when exporting?
