I don't know if this was already suggested once, but sometimes i know about a thread that was made not so long ago but i can't find it. And it's stupid to make threads over and over again so maybe there can also be a community search option, so that you typ the name of the topic, for example search and you find this and whatever other is with search. This way you can quickly see if there was a thread about it and if it's usefull or useless to make a new one about the same thing..
You know the search where the games are? "Games" then "Search box"? They should also have other options there so we don't have to go to the Google search.
