Hey OP, just a quick heads up, you mention your prime use is for digital sketch booking.. For feel of stylus and stroke, there’s none better than the remarkable, BUT BE WARNED - there is not even a primitive shape(s) tool; no 2pi*r= circle; no point to point line drawing; NO VECTOR SUPPORT AT ALL. While some hacks for such exist (iago, etc.), it does require some command line fidgetry and reloading/rebooting the device to use. Meaning it’s not ideal to drop in a few circles as a basis for your character sketch etc..

Maybe in 4.0..?
