Dexmaster / Custom Feedly Styles (+ Always Show Left Menu)

I once used except your CFS also another script (Feedly slimFeed) that artificially show favicons of the corresponding server, and when displaying the All view and view settings Title only, it was too handy.
But unfortunately this script does not work long time ago.
Would he tried you please draw inspiration from that script, and the same or similar function to offer in your amazing CFS?

Old script is here:
https://openuserjs.org/scripts/labm0nkey/Feedly_slimFeed
https://greasyfork.org/cs/scripts/846-feedly-slimfeed
..and here is script with picture of that function, some discussion about it, and some old versions:

Big thanks, Dexmaster!

Just favicons :-)
Colors that were seen in the picture of my Feedly in another issue here is just kind of substitute for the favicons from a dysfunctional SlimFeed script.

Colors are from this script.

Re: @Dexmaster: Many thanks for fixing slimFeed script. I had a few problems - it did not work with GreaseMonkey 3.1, I tried to delete GM and install Scriptish - also icons did not show. Then I changed GM to version 2.3 and with that already works. I tried to update again to GM 3.1 and script works so far.

But I would welcome another small adjustment in slimFeed, which I had forgot - odd or even row has a light green background color. Background color of each open cell is such - I think it would be appropriate to modify these lines in the script:

cssTxt += ".u0Entry:nth-child(even) { background-color:#f6fceb; } .u0Entry:nth-child(odd) { background-color:#f6fceb; }";
cssTxt += ".u4Entry:nth-child(even) { background-color:#f6fceb; } .u4Entry:nth-child(odd) { background-color:#fdfef9; }";
cssTxt += ".u5Entry:nth-child(even) { background-color:#f6fceb; } .u5Entry:nth-child(odd) { background-color:#fdfef9; }";
cssTxt += ".u100Entry:nth-child(even) { background-color:#f6fceb; } .u100Entry:nth-child(odd) { background-color:#f6fceb; }";

..in the past I've tried switch to a background-color:#f6fceb to background-color:#ffffff, but had only just suspect it was in rows u0 and u100, and it would be better to have it changed the author of modification, if you acknowledged that it is coloring even rows unnecessary or not very useful..

Big thanks, Fajfka

Re: @fajfka: I could make something similar in CFS (but better with color picker and stuff) and make small separate script for "feedly icons(favicons) for each row" with only one option and without styling. (I think it would be more productive, also I'll make my own version of it, from scratch and without jQuery)

Re: @Dexmaster: Great news, thanks Dexmaster.

And if the little script to favicons also had to determine its own favicon for the resource manually, it would be quite incredible - I read two sources which favicon is unfortunately missing .. it would be nice if all of the lines looked the same :-)
