[Pen] Responsiveness of pen and eraser

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] There is a lag when writing with the boox pen and the thickness is thin. Also the erasers are not very responsive and require multiple attempts

Describe the solution you'd like A clear and concise description of what you want to happen. It will be good to have a thicker pen or the ability to change the thickness and also to not have the lag. Also more responsive erasers

I can live with it though experience is not very smooth It is nice to have feature. Update: I realised after going through some posts that to unfreeze it should help. I think it did
