Alright, first weekly report in: GSoC 2020: Outliner Weekly Reports
Also, there is now a Windows build of my branch: https://blender.community/c/graphicall/Qmbbbc/
I committed changes to add a new left column for this task: https://developer.blender.org/T68498. It works well right now, and I would love some feedback!
@MichaelHermann though that would be great, I don’t think the outliner would be a good solution because local view is viewport-dependant. So you can have more than one 3D view window open each in local view on different sets of objects. I can’t think of a way to cleanly represent multiple differing local views in the outliner.
@lsscpp @dan2 thanks for the mockups. I prefer either brightening the icon highlight, or the full bar, the half bar highlight has some asymmetry. I really would like to think of something other than another highlight if possible though.
@machieb it’s a bit cumbersome, but you can drag+drop parent in the outliner holding Shift+Alt and it will keep transforms. Making drag+drop more intuitive is on my todo list for the summer.
