I don't even remember the last time when I used KDE. The versions after KDE 3.x were not really my cup of tea. But when Sean mailed me some of his new works, I just had to try KDE one more time. Sean (half-left) is a renowned designer and customization guru who for years have been producing some of the greatest themes and artwork for Linux desktop. And as always, his latest creations are just as good as ever. 3 gorgeous Plasma 5 themes folks.First and foremost, a few things about the latest KDE. So I installed Kubuntu 15.04 on my USB yesterday and have been using it ever since. I got to tell you, KDE over the years has improved by leaps and bounds. Initial KDE Plasma versions received a lot of flak for being buggy and unreliable, especially the Kubuntu implementation of the same. Not anymore. Plasma 5 seems robust, well-designed and packed to the brim with features.I especially liked the new launcher. It is so damn fast! The overall design feels very mature and clean. And the notifications implementation is perhaps the best Linux has to offer in this space. Another highlight was Dolphin file browser, so full of features, yet very light and really really fast. This does deserve a detailed review. Stay tuned.
