Currently, when selecting the "single colour" trail effect mode, the behavior is that when you press a key, that key changes color and there is a speed setting for how long it stays that color before reverting back to the original color.
It would be great if you could add an option that would allow the currently active keypress's trail color to stay active while the key is being pressed-- and once it is released, THEN do the current behavior of having the speed parameter change how long it takes to turn back to the original color.
