This is something that I've always had to modify when installing add-ons that create additional tabs in profile and found they broke onto another line (mainly on fixed width styles) so rather than hijacking this thread with the suggestion I thought i'd create a new thread making the suggestion. (screenshot really explains it).
Yeah this is purely preference. Perhaps this could go in as an option in the style properties? so people could easily change the padding and margin to their preference. I haven't checked if that option is indeed in the style property area, if not, I think it might be a good idea to include it.
