When I need the favorites toolbar, I prefer it to be displayed vertically, so that I can drag in more folders.
Toolbar NAME="Favorites Bar" STATE=right TOGGLE
The problem now is that its width varies with the folder name. If the folder name is too long, the toolbar will become very wide and cannot be adjusted.This will result in a poor layout.
So I hope that if the favorites toolbar is displayed vertically, its width can be set to a fixed or maximum value.
It's better to think like a vertical tab bar.
When using the Favorites Bar, what we often do is just drag and drop the folder,and remove it when we finish some work, without expecting to modify the name of the favorite folder.
Because it’s a toolbar not a panel, and it appears horizontally by default.
Toolbars size themselves.
We may be able to give the Favorites command an argument to make it truncate names to a fixed size, but the reason the two things work differently is that they are very different things.
Your "Left Folder Tree Toggle" label looks like it would be pushing the width out the most; that's a custom button so you can just change the label yourself to make it shorter.
I do realize I could change the width of labels in the toolbar or turn off labels altogether for the toolbar to decrease the width of the toolbar. I was wondering if it were possible to do it at the level of the toolbar itself.
