I see what you mean. Now that you mention it, I've had that same problem.

I looked into it a little, and it should be possible to add manually with some JavaScript, but I haven't got it working yet on Wikia's editor. I don't think there's a simple setting or readymade script you can install. ...at least, not yet anyway >:D

Personally, I think the editor's source mode could learn a lot from the CSS linter they use at Special:CSS. Line numbers, syntax highlighting, vertical selection with alt+click/drag, etc.

...but I think line numbers should be possible. :D
