In Plasma 5.8 development version we have new Discover based on Kirigami UI :)

It it using AppStream for the backend on Ubuntu or not yet?14 Sep 2016
I like it! it looks more organized and clear.14 Sep 2016
Discover is a complete joke, I don't event know what they were thinking when they decided to include an incomplete piece of software. See bugs.kde.org - Bug 362585 – search field does _not_ work and https://forum.kde.org/viewtopic.php?f=225&t=133288
To me, it looks like the developers should focus on creating a stable, bug-free and high performance distro instead of adding new things that break the user experience.
Finally, the overall UI should be more consistent. +Marcin Sągol Since you are constantly posting new stuff here, do you have some kind of relation with Kubuntu developers? is there a place where we can speak with them and share our concerns?
Thanks14 Sep 2016
+Arnau Clouds you can either use mailing list or join #kubuntu-devel channel on irc.
Remember that this is free software and developers not always have time to work on it.
Plasma 5.8 beta will be released tomorrow and all user will be asked to test it as much as possible because developers want this LTS version to be rock solid but without hard testing it won't be possible.
There are various distros that will provide this beta version - Arch, OpenSuse or Neon so grab one and test, report bugs, test more .. :)14 Sep 2016
