Open All Commentaries option
When I'm doing a study on a passage, I frequently want to at least glance at each commentary that's available.
In some instances, you might have 20 commentaries available to you depending on the passage. Manually opening them all is a bit of a pain.
It would be nice to have an "Open All Commentaries" option to save some time rather than manually opening each one for those times when you want them in separate tabs. (As opposed to switching which commentary is open in a single tab.)
You could set up an "All Commentaries" collection then do your searches within that collection.
