Suggestion: Shadow Map Baking Tools for Portal Map Creation

I've been seeing a lot of portal maps being made recently, and while a lot of them evidently have a lot of work put into them, they're being held back by the lack of shadow baking tools. Maps like operation metro (the portal remake) get made fun of quite a bit online because the map looks very flat in comparison to the original versions, and I think a large part of that is the lack of shadows. I know BF2 Editor used to have tools for baking shadow maps for custom-made maps, and I think a similar toolset could drastically improve the appearance of a lot of portal maps, especially indoor ones which can't rely on sun shadows.
