Currently it's only available in the v10 beta. I wanted to release for v9 but then realised it wouldn't work as is. So it's coming for v9 but not there yet.
Yes it's mainly there but the sim wouldn't work in v9 so needs redoing. Currently I'm not sure how many displays it will support. I've tried to write it around the driver ic but looking at the libraries there seems to be lots of variation between devices. For example the display I'm using has a bw option but also a third colour on some displays which I don't currently support.
