During the weekend I found a news message on my Gentoo laptop which said that KDE4 had reached EOL, and that it was recommended to upgrade to Plasma 5. So I did that, hoping for the best, but now I'm finding myself downgrading back to KDE4 for now.
I'll describe some of my reasons, though I would love to find some solutions for them. I do realize that KDE4 is going to go away sooner rather than later, and this is inevitably just a temporary measure. However, as things stand right now, I feel like I would have to invest a significant amount of time and effort into getting things to work the way I want them to, and I just don't have that time right now.
