Add a 'Back' button! Please!

While having a history of previous pages is probably not the best idea, for the same reasons that companies such as gaggle and others, utilising this data to profile their users for advertising, is quite a breach of privacy, there is, however, a great need for a 'One Page Back' button. The amount of times I have clicked a channel and forgotten which channel I was in previously is uncountable.

I consider this to be an Accessibility Topic.
Thanks for considering my concept!
I also want to personally thank you all for developing the Discord Platform, it has changed my life in so many ways! Username: O O#0001
