Is there any way to group edit buttons in MediaWiki?

Is there any way to group the edit buttons displayed above the edit dialog in MediaWiki? By grouping, I mean like Word does (and even开发者_开发问答 this editor) - you can add dividing lines to group them so that e.g. Bold and Italic are in one group, numbered list and bullet points in another.

We've added lots of new buttons (in EditPage.php) and they are in a logical order, but at 30 buttons it is a bit overwhelming for some users.

Why don't you make some fake buttons that don't do anything, but look like dividing lines? Would that work for you?

Maybe check out wikEd, it seems to organize the buttons pretty well, if you can see the code it could help you maybe.
