Handwriting is quite laggy on the Onyx Boox Palma 2 Pro. Although it is usable. Would be better if the app could access files directly in the file explorer rather than needing to be uploaded to the app separately I think. So far it's the only replacement for Liquidext/Marginnote that I've found for Android. Would definitely up stars if the handwriting issue is fixed. still new to this though so I haven't comments about what if you have a lot of files or bigger files.

I have a paid version of this app, The only and very disappointing point of this app is that, sometimes it goes into a sign in protocol , which becomes frustrating at times when you don't have internet access... as you can't access your files without login In..... why can't it be a simple app which serves it purpose ! Please do something about it!
