1) An updated Installer that has screenshots and a description of every program that you install, much like the Zeta (BeOS, Haiku, yellowTab) installer
2) An installer that can grab the most recent updates of everything you select to install during the install routine and apply them, saving you reboots after you install.
3) An install routine that takes only one reboot, not mulitples.
4) An installer that comes with more general software on the disk, so that a first-time user can get on their feet immediately. Include some IM software, media playback, etc etc.
5) More wallpapers that are eCS themed. It's a nice touch to have these things come with the OS. Zeta has a ton of great ones included.
6) Include all the great Icon Theme packages that David Graser has made (not the WPS-Wizard ones, the base Icon Theme ones) so that the user can begin to customize immediately.
7) Improve the installer GUI, its a bit outdated, not not exactly friendly.
8 ) Load every Filesystem driver eCS has available during the install routine so that USB flash drives or other drives (NTFS) can be accessed for the CD-KEY file or other drivers that are already downloaded.
9) Improve the NTFS Driver!!!!!!!!!!!!!!!!!!!!!!
10) New boot process, thats a nice GUI boot. Someone mentioned on the perfect eComStation forum that it should be a wireframe E-ball that fills up the panels of the wireframe as the boot progress, and I think thats a great idea! It should also be at the native screen resolution/color depth so as to look nicer. Pressing ESC during GUI boot would switch to the normal eCS CMD boot and show you all the screens you really dont need to see ever again after the first succesful boot.
11) Scheduled CHKDSK like Windows, so that you can have eCS run the full JFS check when you tell it to, and not have to keep changing your config.sys manually every time. So when you type chkdsk C: /F:3 in CMD, it should say, "Filesystem is mounted, blah blah, complete check during next reboot?" Yes/No and be done with it.
