This forum is for the discussion of feature ideas. These are not requests, and there is no guarantee they will be acted upon. Please do not suggest ports to specific hardware.
If you begin developing one of these ideas, please post the patch to the patch tracker and hold development related talk there.
Please remember that there is this list,
https://www.rockbox.org/wiki/NoDo, of features that for one reason or another will not be implemented. Please do not request them, and please remember that if you write a patch for them it is very, very unlikely to be accepted.
