Shit, im a paint.net user, i should probably switch.
GIMP, the software that's a bootloader away from being it's own Operating System.
Not even close. Try emacs or systemd
Will be interesting to see if they improved start-up time on hard disks. I won't be able to test it because I use an SSD and GIMP starts instantly, but I remember it taking forever on the HDD.
i've only ever used it on an HDD and never had this issue, it starts instantly for me on all my compooters.
