Welcome back Ken.
In addition to some of the items on your list, a few minor things I would like to see:
Allow "last opened" sequence to open on start;
Allow log files to be saved wherever I want (i.e. the cloud).
Do not force new sequence with flats wizard - I use an led panel that is not consistent and has to be be calibrated every session. It's frustrating when SGP's flats wizard requires a close of the current sequence and opens a new sequence, shutting down the camera cooler in the process.
