Just installed, working pretty good.
At first I thought the popup box was empty but now it appears that the text is just white and almost invisible in the box.
Also some terms are getting picked up in the cross-reference while others are not, even though I have them spelled the same and using the same case. This seems to happen when I have 2 or more terms next to eachother or following eachother line after line.
Also when a term is split onto 2 separate lines because of word wrap then the display is slightly messed up.
Feature suggestion

How about the ability to add multiple terms to one definition? So if you want to add ing, ed, upper/lowercase, etc, to the same word that you don't have to make new glossary entries for each.
