There's the info boxes that it could be added to, that way it is always available at a mouse click.

That said, I'm not sure how useful expanding most of the acronyms would be. Names like Negative/Positive Metal Oxide Semiconductor aren't exactly self-explanatory, Vdd isn't really an acronym, etc..

I had an arc 0 where it went through some of these topics more in depth and explained them, deleted it b/c i couldn't get the UI to look right. I've pushed a bandaid that should fix this, but ill bring in arc 0 (it seems this is a popular request) after polishing it (ill also make it optional)
