Can anyone tell me if there is a way to collapse all item groups on the Track Menu List in one go? My projects always seem to have a large number of Props and so I find each time I want to add a new item to the Timeline view, I am having to minimize each of the groups to reach the item I want or scroll through a long list of props to get to items on the bottom of the list. Sometimes it wont let me scroll far enough to reach what I want without minimizing every other group first. Each time I open the menu each group is maximized, so I have to go through the same process all over again. This is really tedious, I'm sure there must be a better way, I just seem to have missed it.

I did complain once... 3 years ago about this underdeveloped feature ( https://forum.reallusion.com/375400/RE-Camera-placement-on-timeline#bm375692 ), but then I stopped using it altogether.
To place an object on a timeline I use Object Related Track button.
That is I keep this button grayed out (OFF) at all times. When I need to place something, I select this object in scene manager, then click Object Related Track twice.
With first click the object is placed on a timeline, with second click that button is disabled.
If you leave this button ON all the time and select an object in Scene manager, everything would be removed from the timeline and that particular object placed (which is also needed sometimes).
Once you get used it, you will forget about Track Menu List.

That's right, I have forgotten about it...

Thanks for that, there's always something new to learn.
