We should warn you that there isn't a guarantee that we'll ever use your suggestion and/or if we publish something along similar lines, you might not get credit. We aren't trying to steal your brain bulbs, we might've already started working on it before you brought it up or someone else might've suggested it first.
Basically, don't put too much work into this and keep your million dollar ideas to yourself. Treat this form as a Google search with no guarantee of an answer.
