Sidebar Lock Button

ASUNDER

Could we get a sidebar width lock button please.

When you use a layout button it will use ratios to spread out the existing tab groups to the template.

But that destroys the custom width of the sidebars. A 'Table of Contents' sidebar, I prefer the minimum width. But sometimes when I choose a new layout I have to drag it back to minimum.

Would be nice to have a lock button to lock it to width. The 'Favorites' bar and the 'Info' bar I would want a little wider, so they would need their own custom lock, so an independent lock feature for them all would be nice. And maybe a custom font size lock too.
