2. If you are within a category the search box will do the same thing as the home page only limiting the search results to the category you are in.
Except it doesn't do the same thing. If I search by username in the category section, it does
find galleries by username. This is where the confusion is coming in.
On any other program I have seen, the search is consistent.
I appreciate that this is how you have chosen to make your product. I was just making some observations, as a user, that I feel might be relevent in improving the usability of the product should you decide that I have point.
