Thank you for improving this addon! This is real helpful.
I’ve noticed that Shift+Click operation does not work properly when I click the “Exclude from View Layer” icon.
Thank you for improving this addon! This is real helpful.
Your welcome! Thank you for your interest and for including the gif, that really helps.
Now for your bug.
It’s actually not a bug, it’s a feature 
But I can see why you would think it was a bug. This is because of how blender handles RTOs. For every RTO except “Exclude from View Layer” if the parents aren’t visible the children aren’t visible, but for “Exclude from View Layer” as long as it’s checked, it’s visible (provided you haven’t disabled any of the other visibility RTOs for that collection). So for the isolation feature I do the best I can, “Exclude from View Layer” gets properly isolated, while ones like “Hide Collection” get isolated as much as possible i.e. their direct parents stay visible as well, but nothing else.
To verify what I’m saying add a monkey to the layer you’re isolating and try your test again (leave the cube where it is). “Exclude from View Layer” should show you just the monkey, while “Hide Collection” will show you both both the cube and the monkey.
Let me know if this is clear enough, or if I’ve misinterpreted your report.

Thank you for the explanation.
No problem.

Small update here.
Added an isolate tree feature. This allows you to shift-click on an expansion operator (the little triangle) and it will collapse all other collections except for that collection, and its parents. It leaves the descendants unchanged. Expand/collapse all sublevels has been moved to ctrl-click.

To anyone wondering, I know it’s been a long time since I’ve posted an update here, but I haven’t been idle. Something major will be added to master shortly. Those of you who have been following the development task (T69577) will know what I’m talking about.
Hello,
the addon is fantastic! I want to ask if it’s possible to add a feature where you can expand or collapse the collection without sub-collection???
Thanks!
Not sure what you’re asking for here. Currently clicking on the little triangle expansion operator will just expand or collapse that collection. It will not touch the status of any other collections, so if none of the sub-collections are expanded it won’t expand them. However, if you have a whole tree expanded and you collapse the top collection and then expand it again the whole tree will collapse and then expand again. But I know that sometimes you want all children collapsed or expanded so if you Ctrl-click on the expansion operator (Shift-click if you’re using blender 2.82 and not 2.83) it will completely expand/collapse all sublevels (I’m hoping this is what you’re looking for).
Apologies if I’ve missed what you’re asking for.
Sorry about that, it’s better to show you a picture:
as you can see there is no subfolder, just objects… The main folder only contains these objects. I want to know if you can synchronize the collection manager to the outliner, where I can just expand or collapse without using subfolders.
is it possible or not? that’s what I would like to find out. Sorry to trouble you with this question.
No trouble. This is much clearer, thanks. There is no object support currently, but it’s tentatively planned. Unfortunately, I don’t think syncing the expansion status with the outliner is possible, but I’ll keep it in mind if I come across anything new.
Alright… good to know. I just tried the collection manager and i can tell it’s syncing with the outliner… it’s excellent. Of course I was testing to see if i can hide or unhide the main folder of my choice. so yeah that went well.
I’ll be looking forward to a day where I can use collection manager to expand/collapse the main folder and hide one of objects!
Good luck.
Thanks
Update! Version 2.0.0
New Quick Content Display (QCD) system.
This consists of a 3D View Header widget and a floating panel similar to the layers system in blender 2.7x, along with hotkeys to view/move objects to QCD slots, and additions to the main Collection Manager popup to allow you to manage which collections correspond to which slots.
Note: While QCD slots are saved to blend files it’s not entirely finished yet so you may have to redo your QCD slot numeration in the future.

HI @Imaginer.
Do you plan to create a demonstration video to explain how QCD works?
Also, it would be convenient to have some information in the preferences about what QCD is (in tooltips ?):
I think that new users of your addon might wonder what it is, or how to use it.

Hi @xan2622
I’ve wanted a video about the whole collection manager (including QCD) for a while now, but whether I end up making it or someone else does I’m not sure. I keep hoping one of the popular blender youtubers will find out about it and make a video. 
Sure. I can do that.
Hi Ryan,
im not sure which thread you watch more closely. Ive noticed some heavy CPU calculations going on since 2.83 update.
i posted in the dev thread
https://developer.blender.org/T69577
Looks like v.2.4.1 fixed some drawing issues. I havent read all so im not sure what the issue was
Perhaps show those hotkeys in the addon? or state that hovering will show them.
Also in 3dv should ctrl + click move items from one collection to an empty spot or to a different collection. It doesnt do anything for me on OSX 2.83?
EDIT
Okay did restart and now does seem to move items. But the other keys alt + number or alt + shift + number dont work. But thats due to me using emulate numpad
Still not sure about showing those 20 icons, i thought that was abandonded. I think makes more sense to only show Collection if there are any. Would also be handy if that tooltip showed the collections name above the shortcut
Yes, v2.4.1 fixed this issue.
I’ve updated the main post here with a note about this. Thanks for mentioning.
Those are needed to accurately show the current state. You have 20 possible slots, but not all of them will be in use all the time and they can be set to any collections in any order.
I can see how that would be useful. I’ll see what I can do.
They’re about the same, so you can just pick one.
