All your suggestions look very good, and interested.
For me the number 1 I don't have problem to wait the whole calibration routine, but I understand that maybe other want to do a quick calibration, so instead of calibrating all the points just do the middle point. (this was possible before when you import the gcode model hitting the import button the printer will do just the middle point calibration but it was removed later).
The number point 2 it will be very helpful for more advancing techniques of printing.
Number 4 for me is a must, to keep the printer always lubricated. it will be very helpful if flux studio could alert you before hitting a specific accumulated hours to make maintenance.
