My first suggestion is a non-systemd version. I have tried S6 recently and the boot speed is amazingly fast, maybe the fastest among all of the init systems, currently only 2 distributions supports S6, I wonder if siduction could make a non-systemd version and shipping with S6 that would be the best.
The second suggestion is a universal installer instead of providing multiple desktop editions. I have tried Endeavor OS and I must say the installer of Endeavor OS is my favorite so far, I can try to install a different desktop environment without being forced to download another iso file and I really like the traditional Gnome2 looking Mate desktop, Mate is super efficient with the traditional menu
The third suggestion is better wireless adapter support on installation media. I downloaded the KDE and XFCE version of siduction, both of the installation process can not recognize my USB Wifi card, that's really inconvenient.
