Font size in popups AND multiple references?!

Coming from Bibleworks, you could 1)control how many and which Bible versions to pop-up on mouseover text and 2) choose the font size per language, so the sizes of Greek, Hebrew, and English were independent. I've often assumed Logos could do neither of these things, though I really wish it could.
But then, look at this! The popups from the BHS apparatus are 1) larger than my other popups and 2) in two versions!!
For comparison, here's the (sometimes) size of popups in other resources. Other times, popup text is much smaller.
So, is there a way to make more than one version pop up regularly? And how do I control the font size?
