While DXT2 looks simple there is a lot under the hood that you don't see. This is an attempt to both modernise and speed up Buster & XFCE, while still working well on old hardware. DXT2 will not bug you with unsolicited popups & other visual "features", it will let you get on with your work in peace.
It does not feature many super extra cool themez & stuff, nor does it have any major software besides system utilities. Everybody has a different software set they use, so try not to judge it on this.
If you like & use DXT2 but think it could be better then voice your opinion, several features have already been implemented based on user feedback. DXT2 also has a sister Xevuan, a systemd-free version of DXT2 based on Devuan.
