RayBe,
this posting idea thingie is two edged sword. On one hand it is a good idea, on the other hand it is a nuisance of a couple of the devs who take it not like a discussion of what is nice to have, and how the person having the idea is going to implement it, but more a: I have this great idea, go and implement it!
If you have an idea, go and start to implement it. Do baby steps, read the programmers guide on the wiki, read the source code. Setup a build environment. All those things are not easy things to do, they take lots of energy, persistence and time. If you are willing to invest those, and you come up to a stumbling block, ask a question, detailing what you have done. People will help you. Mind you, this point won't come in a week or two. But if you stick with it, you will have something to be proud of in 3-4 month time.
