A few new app icons.
Added an rcc file to the SMPlayer theme.
I'm glad you like the theme.
For an icon set, the "source" is usually the set itself. I made these icons by using various methods with Inkscape and Krita. Most of them are SVG-based but, most of the time, I didn't just exported PNG from SVG. The SVG files are a such mess that I prefer to focus on creating icons with high quality rather that doing the boring task of organizing their SVG origins.
That said, a simple Makefile and a debian folder could be created to package the whole set into a deb package, and a similar thing could be done for rpm too. That's rather a distro job though.
Thank you for telling me about "apps/application-x-clementine"! I'll make a symlink for it with the next update. For now, you could do that with this command in all apps folders and then recreate the icon cache:
ln -s clementine.png application-x-clementine.png
The forward/backward button issue doesn't happen here. The versions of Konqueror, Dolphin and KDE are all 4.11.3 here.
After searching for the icons you mentioned, I found that they belong to Gnome or other GTK-based environments, not to KDE. In KDE, the names are different and the corresponding icons are all included.
I'm glad you like the theme.
The icons you mentioned don't seem to have standard names. I couldn't find them anywhere except in Ubuntu Trusty. However, I'll surely add them by making symlinks if I know there has been no mistake in Trusty's packaging. Thank you for telling me about them!
Thanks a lot
As far as I know both DEs, I can say that KDE handles darkness more easily than Gnome (only Oxygen has some problems with very dark themes but you could use QtCurve or Bespin). With Gnome and GTK+, you should apply several workarounds but with KDE and Qt, it'll be enough to change a few color settings (in Kate, for example). On the other hand, Gnome breaks themes with every new release -- no exception so far!
In fact, my first reason above for uploading the set to dA wasn't quite accurate. It would be easier for me to upload it as tar.gz to my dropbox account and put its public link in kde-look.org. However, here I get really useful feedbacks, which I don't get at kde-look.org. Feedbacks are important to me because they could make the set more complete. It was a surprise to me to see Linux users more active here than at kde-look.org.
Thanks a lot for the explanation. Here are some facts and my opinion:
(1) There's no need to log in for downloading from dA. WebUpd8 and NoobsLab teams are so kind that they make deb packages from my other themes at dA. So, I don't think dA is an obstacle to packaging;
(2) Sadly the SVG source is a real mess and I prefer to use my free time for making the set better instead of doing the tedious task of organizing and cleaning the SVG icons. On the other hand, most icons are more than exported PNGs;
(3) 7z is an open-source and really good archive with a very high compression ratio. All distros support it (in Debian, p7zip-full is the package). Ark supports it too. For heavy backups I even prefer it to tar.xz because a 7z archive is created and extracted faster and has a smaller size.
I don't know why some people dislike dA. I take that as their personal perefences, which I respect. That said, I don't see any objective reason for not using the comfortable space dA provides.
