Are you talking about going across the power supply connection?

I've seen .1uF across individual chips, a lot.

Yeah it is. But that's pretty non-critical, too. Look in any sort of scrap
electronics you may have laying around, see what they use, it'll vary...

Makes sense to me.

Don't know why you'd want to do that.
