I did so. The name length limit may be changed with a command line argument. I also replaced the gtk.ListBox widget with gtk.FlowBox w/ gtk.Buttons inside. This allowed to format the output in columns. The number of columns is configurable as well.
The GitHub repository is now public and ready to beta-testing.
@SGS - I hate telling this, but I have to.
Several people pointed out that the existing nwg-shell logo evokes associations with Christianity, the Middle Ages and the Crusades. The graphics is very good and I'm grateful to you for designing it, but I decided not to use it any longer, for ideological reasons. The new logo will be neutral, with only "N" and "S" letters inside. Please don't be angry with me. 
Thatās not a problem for me. 
I canāt be held responsible for associations, the logo is the result of the process, which you can see here above.
We both know it well, but the audience doesnāt.
Frankly my dear, I don't...(fill in the rest, famous quote) (about logo). If you want to use it and reminds people of a murderous giant fruit bat with grape jelly on it's chin..that's up to you 
I'll try to git-up and take it for a test spin in a bit. Still feel not quite awake....even though I've gone shopping already.
If only had I known! I run out of beerā¦
Well, in the plain view it would be a solution, but I'm afraid - not in many possible variations.
If you make the outer area transparent, then yes
I think I'll stick to this one. It's safe and looks not bad, doesn't it?
If you fix the glitches, "errors" yes.
Use backward search for pictures 
Well, I played with it. I found 10 to be about my sweet spot (but depends on screen) for the # of columns. It performed fine.
I like that you're (explicitly) deduplicating (lol) and confirm I have no dups (yay).
Thanks for testing!
I use 6 columns, as they need to fit also my vertical output.
-nows and -nolauncher arguments to disable the workspace switcher and the launcher button (closes #10);nwg-drawer or nwggrid command, if available.All caught up with your current releases. Enabled nwg-dock for the first time as a system component of my desktop. Looking very slick overall.
You should push the set to the AUR (some already there I think?).
Well, building gotk3 for the first time takes 10-20 minutes, depending on the machine. If AUR at all, than it would have to be -bin packages. I'm not sure if it would be acceptable.
Well, compared to building firefox and it's derivatives which take about an hour...I don't see that much issue really ? Of course, just a suggestion.
I'm still unsure what to do. I'll decide sooner or later.
