OK ... I didn't know this, I didn't see it explained in the wiki but there is a screen print showing it even in L4?
When I'm studying I almost always have my Bibles set to 'Text Only' so each line is a verse. I keep a bunch open and quite frankly I literally can't see the verse numbers. Go figure. It's a Bible!
But when you use 'Text Only', the little notes disappear. That's not good and I don't use the lookups, information panels etc since I'm on 5 different windows.
But for some odd reason if you use the Text Comparison panel and you set it to the left-A, the little notes ALL APPEAR for ALL the versions. WOW. I don't care about the 'differences' since it's kind of a nutty exercise in english (luckily they're in grey and not really clear). But I DO want to see ALL THE NOTES on ALL THE VERSIONS. AT THE SAME TIME!
This is great.
