I love this idea, would be great to initially see who is on Xbox and who is on PC until the profile picture is changed.
I love the idea, but I also know that there is a lot of malicious people on the internet. If Mixer allows custom gif's - I do not doubt that we'll see all kinds of X rated and even worse things show up everywhere.
Unless Gifhy is actually moderating that is on their site, but I never use it, so I don't know.
But yes, I am 100% for customization as long as it does not come with the option for trolls to run wild.
Great idea! :D
