No Plasma developer is involved with Kontact/KMail and Konquror is not developed at all.

Try Yakuake.

Um, duh. Plasma 5 is by far the best looking desktop out there. And if you don't like the default, well, it comes with four other Plasma themes, two icon themes, three window decoration themes, and five app widget themes (two by KDE and three by Qt itself).

Apparently there is enough choice already.

Congratulations, you are among a tiny minority of 2%: https://forum.kde.org/viewtopi...

The story is about openSUSE Tumbleweed, a rolling release distribution for advanced users.
Regular openSUSE still comes with Plasma 4.
openSUSE 13.3 has not even been dated yet and will come with a future Plasma 5 version.

Apparently you use (K)Ubuntu: Their QA track record regarding anything by KDE is absolutely horrible and their reputation for jumping onto new features way too early. Read the "Suitability and Updates" paragraph of https://www.kde.org/announceme...
KDE has been absolutely forthcoming. Plasma 4 is maintained until at least August 2015 for a reason.

Only a single (!) major distribution shipped Plasma 4.0 exclusively. That was Fedora. All others either shipped it next to KDE 3.5 (like openSUSE and Kubuntu) or waited until 4.2 (Debian, Mandriva,)

Audacity does not have true surround support. The individual tracks can be mapped to a channel when saving. It's not a smooth way to support that feature but it's way ahead of the competition (i.e. GoldWave etc.)

Quote from TFA: "I often ask myself what the current state of video editing is for free and open source software (FOSS)."

Does this wording really mean "proprietary software under Linux"? To me it does not but maybe that's because I'm not a native English speaker.

Have you ever tried simple wave editing in a surround sound file?
Among the non-professional / low-end tools Audacity is apparently the only wave editor to support that at least to some degree (although the channel mapping window when saving is awkward).

In the end I used ffmpeg and SoX

And others say Reaper, the product of former Winamp developers, sucks and you should use Ableton Live instead. Others say Logic Pro.

I'm not a musician myself but I know a few and each has their own preference.

I had to do some simple editing (changing speed and so on) in a 2h audio file a few months ago. GoldWave 5 was completely unusable â" it just crashed. GoldWave 6 beta worked but at super slow speed on a 64 bit Win 8.1 Core i7 system. After 15 Minutes of waiting for the FLAC file to save, I just gave up. (GoldWave was my first wave editing love, so if anything my opinion was skewed towards that.)

Audacity was (and still is) not pretty but unlike GoldWave it worked. I prefer working software over non-working software and as simple wave editor Audacity does the job.

First, please provide proof that FOSS developers in general do not care about stability, as you claimed in your first post.

RTFA!
The article claims to list "6 free and open source video editing tools" and includes LightWorks in that list.
That's my point. And now GTFO.

Your attitude to claim that all FOSS developers just accept crashes makes you spoiled.
Not every bug is reproducible everywhere. If a bug does not occur or the developer's system, it's not his fault.

If you want something like Adobe Audition, you should get something like Adobe Audition and not try to use a simple wave editor as DAW substitute. Get Bitwig Studio: https://www.bitwig.com/en/bitw...
I heard it's by former Ableton people, so they know their stuff.
