Hi phlatt5th, Happy New Year!

At the moment dashed line styles and text displayed inside of a viewport are still not implemented quite yet in v4, the lack of the XYZ axis icon labels and the blue background title are just temporary. I will be working on those areas once I've cleared out the list of new bugs.

re: scripts - you can run your scripts with V4, several of Max's have been updated which you can get from his file repository here: http://moi.maxsm.net/media/files/ . If you're using any of the ones at the top that have been modified since Nov 2017 ("NutsAndBolts" through "Gear") you should get the updated version there. Also I think the CustomUI extension is not quite ready for v4 as-is.
