Bottom Screen splashed should be easy implementable, but I the bottom screen always for the log, and I would like to make it possible to keep the log and make it possible to integrate it in the splash.
But I don't know when I will do it, but maybe I will do it, after I upgradet the a9lh fork to a9lh2, together with different log levels to allow the displaying of some informations like waiting for a key or asking for the boot passoword, without all the other logging stuff.
Also in theory you could also use a much longer duration for the button press check.
