My idea is next :
Implement a search option for maps in Map List. There are now 3000+ maps and its really hard to find a specific one and, well boring. So my idea is make search option where when you type just a fragment of map name it already gives you a narrow search(something like Google search). For instance if you type cast.. it already gives you a suggestion of maps that starts like that or has those letters in its name, castle fight, castle defense etc etc...
