is it possible to do that without adding the icon to assets?

ahh.. my mistake, you added it to the online page.. I was wondering if it's possible to get it working with the offline page as well

Thank you @Trapsta

I'm not sure if that favicon is the best representation of upup.

I created a lame one that uses the name of it from the demo page. Unless you have a suggestion for a better one, I suggest we go with that one - https://github.com/TalAter/UpUp/blob/master/demo/img/favicon.png

If it doesn't look great, we could always fallback on the plane emoji.
