I have many decks and many sub-decks and I tend to tweak their settings quite frequently.
Also, I am using the add-on Enhance main window, which makes for many columns and a very wide distance between the deck names and the settings toggle.
It would be very nice to have the options to set the rows in alternating color so that accessing the settings toggle for the desired deck is easier.
For me this would just be more pleasant to look at and easier to read in general as well.
Thank you for your consideration! 
(I think I have read something relating to this suggestion before, be it on the anki forum or maybe in discussions of that add-on but I am not able to find it right now; please forgive me if this has already been addressed.)
