Drive Buttons and Drive List alignment options

I'm having trouble keeping things aligned in the drive toolbar when resizing the tree or the lister etc. even using spacers.

Could the Drive Buttons and Drive List be given these kind of options similar to what is possible in the status bar?

rtree - align to right edge of Folder Tree
rtree2 - align to right edge of second Folder Tree
rleft - align to right edge of left-hand File Display

The file display toolbar is intended for things you want to line up with each file display, and the best way to do that kind of thing.

We don't currently plan to allow for alignment of objects on other toolbars like the status bar can do, but anything is possible in the future.
