Here's a crummy drawing i did in my tablet's drawing application of a "semi-graphical" deblet installer that would display a progress bar, terminal window (for seeing what's accuring), a options window that displays the options that you've selected and would display a estimation how much memory you currently have left in your deblet partition and how much it will take up after the install, also It would display technical information about swap, upload/download rate, time estimation, etc..

Stskeeps- Btw, have you ben able to get those packages that i provided you set up (nit-env-gnome-full and gdm-autologin)?, just wondering.
