@Sprinklednights Some programs are written specifically for KDE, but if you can find replacements (I think the only ones without are like, Krita and Kolourpaint, maybe), then yeah, it's nothing.
Actually, Slackware switching from KDE 3 to 4 made me seek another distro then (this was somewhere in 2008). That was before I knew how to, like, just install all the packages I want myself etc. But I knew enough to drop a trash DE when I saw it. And KDE 5 is even worse.
