I did think about doing it that way but sometimes I can't recall the
name of something I'm looking for and just have to scan down the list. 
Breaking it up that way would complicate the matter because I'd have to
go look deeper.  As time goes on, I'd have to break it up even more
which would result in having to go even deeper.  There may be a way to
do it with linking or something but that could get interesting too. 
I've already got some divided up but even that causes issues sometimes. 

It's interesting, having all this data is neat but it can cause brain
teasers to sort through.  ;-)  I'm still considering that Raspberry Pi
thing tho.  Small, power efficient etc etc.  Lots of ideas.
