you want it to watch some clj files? What's the goal? What i've done, if I care about clj is to write a little macro that triggers a rebuild for specific file changes. Not a common thing though. But in general, i've yet to run into performance issues and when there are hiccups it's easier to resolve the specific problem that try to solve something that's yet to happen.

I was curious to try putting all my clj, cljs files in one directory, rather than src, src-cljs, etc. And since figwheel watches a dir it would reload everything by default. But yeah, probably not something to be concerned with at this point, thanks.
