That's hilarious. I'm on Tumbleweed as well (most of my systems are either Tumbleweed or Leap, and just a few specialised ones are Gentoo). So why don't we already have it packaged in openSUSE? :D

Sweet. I actually have a slightly more updated ebuild for plasma-mobile, as well as an ebuild for plasma-phone-components, that's not posted on the Gentoo bug tracker yet, I should probably upload that. I am in fact succesfully running Plasma Mobile on my tablet already. It's far from being ready for daily use, of course, but the basics work fine.

For me, "Plasma Mobile" in the strict sense is a Plasma shell optimised for touch input. That's what the name implies, after all. Basically I see it as the successor to Plasma Active and the overall concept of Plasma adapting to one's hardware dynamically. Obviously for it to be useful there need to be other utilities that are touch optimised as well, but that's Plasma Mobile only in the loose sense (and actually KDE Applications). I find the other things (Kirigami etc.) to be their own projects that integrate well with the shell.

Actually Xournal also has PDF annotation features. But there's a broader point: as a former Mac user, let me bring up the unfortunate truth that Okular can't hold a candle to Apple's Preview, *especially* in the annotations department. That's the standard Okular needs to aspire to. Right now Okular's annotations have a major problem: they aren't consistently compatible with viewers that aren't Okular. Annotations are often not visible when printing or viewing with another problem. This is of course tracked by many bugs:

Reading the thread, KBibTex was not cited. It is an interesting bibtex manage software, in KDE4 times there was an integration with Kile. KBibTex was ported to Qt5/KF5.

FWIW, there's some ubuntu PPAs with daily builds of the KF5 port. i'm using one for work for quite some time now. if you have something particular on your mind, we're always happy for suggestions. we know that a stable release is overdue (the latest stable 0.6.5 still uses KDE 4). please help us find issues that still need fixing. i guess we should keep it about broader strategy here, and discuss particular technical issues someplace else, right?

I am interested in this, and specifically for the case of amd64 tablets (I'm biased because I have one :D And have been looking forward to something like this since the age of Plasma Active). Right now GNOME is really far ahead in that use case, since Plasma Mobile assumes a phone (and so portrait mode, dialer, etc.). Also DPI scaling needs more work. And the ability to switch between Mobile and Desktop would be sweet (as it is, I need to uninstall Desktop to be able to access Mobile, seemingly).
I've also written a post on my impression of the current state of Plasma Mobile in comparison with other mobile UIs on my blog.

That's a nice idea. I'm involved with a course that introduces Linux and programming concepts to students and I'd love to see more KDE representation. Last year we used XFCE, this year we'll most likely be using GNOME Flashback.
