Hmm I have always been in the wayland world (KDE,Hyprland etc.) but I have been on xfce in mxlinux and I didn't need to do primary selection & middle click

I don't know if tinycore supports this. This was my biggest grievance because I had to create tmp files paste into it and then cat into it or something to work with this pain (which I feel like is pretty fixable/ maybe a skill issue from my side and honestly wishing for me to learn how to fix it)
