This is true 100% of the time.
- In the Plug-in Manager, have at least two top-level folders, and have the first top-level folder contain subfolders. Do not have any plugins in the top-level folder; only have plugins in the subfolders.
- In the first top-level folder, try to move a subfolder to the bottom-most slot. Release the left-click.
- You will see that, rather than being moved to the bottom-most slot, the subfolder is promoted to a top-level folder.
It is therefore impossible to move a subfolder to the bottom-most slot in a folder.
Here is an example:
I run into this issue very frequently. The (quite tedious) workaround is to drag the folder to the second-from-bottom slot, then move the bottom-most folder above it so that the intended bottom-most folder is now in its place.
Steinberg, can you please fix this behavior?
(Bonus: I also find it quite annoying that the folders auto-expand if you are dragging plugins to them and hover over a folder for too long. It would be great if they would just stay in place, and perhaps a right-click would expand them. Or if that behavior was optional, etc.)
