Hack your UI!

The decimals allowed in the basic UI make fine tuning alignment a royal pain. But, you can edit the xml files and fix that! This wonderful person tells you how.

(Hint: search for 'name="ColorTrans"' in the tools too, and up the max_val from 90 to 100, and be able to set things ACTUALLY transparent without scripts or textures!)
