Hi, I originally posted this topic at the newbie forum last week (
https://forum.cockos.com/showthread.php?t=207593), but found that it was probably a Mac-specific bug, so I re-post it here.
The issue is that the folder expand/collapse button on a Project Bay list works only when the column ("Active take name" column in "Media Items" tab, or "File name" column in "Source Media" tab) is positioned at the very left of the list. Otherwise it doesn't work, and clicking on the "+" button just opens up a small pop-up window instead.

I also found another Project Bay-related issue, which is rather minor one but essential to my workflow. I don't know whether this one is a Mac-only issue or not.
A shortcut added to the action "Item navigation: Select and move to *previous* item" works even while the Project Bay window is focused, which is very useful, especially if you combine it with other actions.
However, a shortcut for the action "Item navigation: Select and move to *next* item" doesn't work when the Project Bay window is focused, so I have to re-focus on the main window to make it work.
I use Reaper ver.5.91 on Mac OS 10.11.6 El Capitan.
Thanks!
