RE:
Improved SearchBar
Maybe also prioritize users that start with the search string rather than all that include it. For example, when typing "st" there's a higher chance I am searching for Stinkyfish than Lynyster.
But on the other hand, I might be searching for ThomasStoop and I just forgot the first part of his name. So I guess it depends whether you mainly want to make it easier for people that already know the (start of) name of the person they are searching, or for people that remember part of the name that is not necessarily the first few letters.
