[Bf-committers] Sub-groups in Blender now and then

[Sam Vila]

Hi, I have a question/request: based on this video:

Looks like the old 2.48 versions had the ability to create sub-groups when
you're linking objects, that's very sweet and keep everything more
organized but I've been trying to achieve this in Blender and I couldn't
have it to work not only in the new 2.6x series but even in the old ones.
So my question is... how you achieved that in the early days? it would be
awesome to have an option to organize the groups in different categories as
it's shown in the video.
