Dark mode + More social support Adding dark mode as an option instead of browsing the bright ocean of VidLii, and an embedded chat room or something similar [maybe even an IRC, hell if i know.] If you can't do that, add more optomised support for the VidLii Discord[s].

Youtube logo make a option to choose from old youtube logo or vidlii's logo :D

Sonic shirt the sonic shirt explaining everything

progress bar color affects all of your videos For example, my progress bar color is dark and red, if someone was to watch my videos they would get that color on only my videos

Video Page Version I think the Vidlii site is good, but if the user (im saying the one who will upload the video) can choose how he wants the video page to appear (like which version the video page will loo like) for the viewer.

I love Vidlii
