or even better, personalized color themes, that way we can have all the shades of pink we may want!
Telegram is doing it already up to a certain extent.
I always love it when apps let me choose ANY color for each item in the interface... or better yet, images! So you can make things have a different texture and have something cute as a background image or have Shrek's face all around if you like that :P
No idea actually :P I found it randomly but I looked for it again and found it on Deviantart by fauzi1998 with no watermark and the Edgerunners logo on it (also it's apparently an animated wallpaper) and with reverse image searching I found it on a website called konachan without the Edgerunners logo or the shadow seen on the deviantart wallpaper but with an easy to remove watermark that says @Lm_akko
I've also seen the deviantart one reposted on other 3 sites for wallpapers and the konachan one reposted as a browser theme without the watermark
There is a twitter account named Lm_akko but twitter won't let me see it without creating an account but it looks like that might be the artist
