Is there a page where we can post ideas for next firmwares

?
For example, I think the scroll for light is too difficult to set, it should be interesting to have a "-" and a "+" at each extremity of the bar to adjust the light
one by one... it's not a big work for developers and a lot of people could be interested by this add. So where can I post this suggestion ?
Maybe some people have other ideas that could be quickly integrated in next firmwares if thoose new functions do not need too much development...
Last thing : Yoq and kevinshort have made a big work around the "night mode", why not integrate it into the firmware because it's THE basic function that a lot of people use (all the others marks/models proposed the function like amazon/kindle, etc))

?
