At least as they have wound up being configured for me, popups in the web app are so much better than in the Windows app! In the web app, I'm looking at the popup that results from my hovering over a reference to Isaiah 53:4-12. First, even though the font size for the text of the book I'm reading is large, the font size in the popup is small.. Second, the cited verses don't fit in the popup box in the web app, but instead of the elipsis after a couple of verses that I get in the Windows app, there's a scroll bar, because the entirety of verses 4-12 are in the popup. It's so much better to view the entirety of the cited verses in a popup than to have to click on the citation, read in my preferred Bible, and then switch back to the text I was reading! I wish the Windows app worked like this.
