Make Search more prominent on the "explore" page
The main way to find an app in gnome-software is likely to be via search.
The explore page has a lot of design for navigation and categories, which are probably useful as an introduction to apps and for new users.
However very little prominence is given for searching, which is likely to be the main function to be used by returning users. Search starts by default when you type, but there is no visual indication of that.
There is a button in the headerbar, but to be it doesnt come across as prominent enough for what will likely become the primary action of users returning to gnome-software.
