I would be happy to help you. Thanks for being a part of our family for so long!
I totally understand the inconvenience of having to reorder the songs. Unfortunately, the formatting is just so vastly different in Version 7 since it's a brand new platfor with new code and new ways of handling the libraries, we could not bring over a lot of elements from the previous versions. This version is the cleanest version we've released since Version 3, as it does not carry forward any old code. Some of that old formatting done in the old way was carried forward from 3 all the way to 6 and it actually greatly affected performance and stability. So to be able to move forward and upward, we had to make a clean break in some areas. I'm afraid because the library format was one of them, it just didn't read some fields such as the play order. With that said, we are working on an "import" tool for V6 complete scripts. That will allow you to bring in cues with all formatting including background, etc. So that will be an option to bring in songs already formatted to save into the cues library. We expect that by the next update.
Regarding pagination and page breaks- this is another thing that you'll have to set in Version 7. But it definitely can be done. You just right click in the verse text and click page break, or press Ctrl + Enter. Once you have the song formatted and split the way you want, you save the song to your Cues Library for next time you need it. So the shift is that the lyric library now is mostly just a raw text database, and the Cues Library (for any type of cue, not just lyrics) is where you'll store songs and other cues that have the play order, formatting, page breaks, and even background that you want. The page breaks are done in the editor once the song is in the script, not the lyric editing window.
I'm so sorry about any inconvenience with this workflow. I think it could definitely be a good feature request if you would like to add it regarding the ability to add page breaks in the lyric editor, so they're stored that way within the raw text library, if possible.
