Documentation.

Please add a keyword search of all documentation similar to the one you have for the forum.
I can find subjects on the forum far faster than in the documentation all because of that one little feature.

Honestly, a lot of the most important stuff is found in the game news. I often use a browser search on that page to refer to the most important updates. For the game documentation, there simply isn't all that much there. Spending thirty minutes clicking through the categories can give you the general gist of where things are located. After that, you will likely simply go back to refer things like game level requirements, weapon data, score penalties, and c3 defenses.

Here's an idea - if the Game News was transported over to the forum, the keyword search would work as normal. Just click on Topics, and Game News would be at the top of the list, right above General.
But, as you said, once one finds Game News, a simple browser search works just fine.
I'm sure the GMs have already considered porting the regular game docs over to wikidocs and letting the most experienced players keep the docs up to date.

Meh, just some thoughts.
