I think a neat little feature that could be added to the tags page would be a search bar. That way users could find the tag they want more easily!

For example: Let's say you want to set your profile pic to a giraffe, so you go to the tags page and have to scroll a long way to find at least one giraffe picture. This takes time off of you, and it can be frustrating to scroll or look in the categories for more than 5 minutes.
Now imagine if you had a search bar, you could simply type "giraffe" and get the results instantly! It's quick and easier for users!

I know it's not a priority since there are features of the site that require more attention and are far more important, but I just wanted to propose it!
