Ok, I see how to account for the realtracks. Using the stylepicker is not how it's done.

Instead:

Under the "Tracks" group (group in far-right-bottom corner of the window with all the buttons, song title, etc) click on the Saxophone icon labeled "RealTracks" with the down-arrow. Then click "Realtracks Picker Dialog". Or shift-then-click the same icon. Can click the "Copy List ..." and cut/paste the result (opened automatically in Notepad by BIAB) to a spreadsheet. Doing so, I count 2,106 RealTracks. There are "holes" in the numbering - but 2106>2000 is all I was looking for. I'm sure everything landed.

The software does have some "quirks" around the RealTracks as I would have expected all of the RT### sets to show up in the "StylePicker". But perhaps the StylePicker is not the right tool to pick all RealTrack sets and there are cases where StylePicker is blind to a RealTrack.

9) I have loaded a song saved with 2015 which had a tag (coda) and in the coda some holds. Loaded in 2016, the ending of the song is not showing correctly during playback. When playing the tag (which shows up fine all in the same 1st "page" under the "chord sheet" - when the tune gets to the tag, band in a box decided to "turn the page" into the dark-grey past-the-end-of-the-song area. The paging wasn't correct since the song sounded as playing the tag which is in the light-grey area.

BIAB seems overly aggressive with the focus. The entire song fits on the page - so there isn't a need to shift around which measure is at the top-left. Instead, the display is "going off into the weeds" although the playback itself is correct.
