Option for homepage title to put site title first (not catchline/secondary title)?

I know this has been discussed before (somewhere), but I'd like an option for to switch around the main title and catchline/secondary title of one's website for the generated title of site pages...at least for the homepage?

I get the logic behind having each generated site page list the site area first, then the title (e.g., "Forums - LiquidFractal"), but my current homepage simply includes the catchline first, then the site ("Crystallising Open Learning - LiquidFractal").  This really doesn't look very nice, so I was hoping I could switch them around at least for the homepage, which would look better in searches, bookmarks, etc. since my business lists them the other way around in the first place...

I'm pretty sure someone somewhere once wrote a plugin or something which does something like this, but I'm not sure.  Anyway, it would be a good idea to control it at least on the homepage.
