Some clarification needed about new product and firmware

Hello, I saw you promotional video and I'm really happy about the new device and firmware update, after the max3 I bought I'm interested to buy a note air2 but first I would some information if possible. - I see you have implemented a new film that is part of the screen and should also improve the writing feeling. You have also developed a new book pen that it's nice, but honestly I'm a little tyred of chance always the nib. For this reason I would try a suoernote pen with ceramic nib, do you think that I can use it on the note air 2 with the new screen protector or it can scratch the screen? Can you investigate please? I would be happy to scrivo e some writing feel for a permanent nib... - I see that you have developed the drop boox app, it's seems very nice but I think that it would be game breaking only of we can synchronise also note on native format and not only as pdf, on this way we can move the note we want one per one on the PC. So how it works? It syncronize note only as pdf and pnj or also on native format? I think this is the real thing to platform lack. - Lastly I want thank you so much for the favorite pen slot, that i think is pretty useful, I asked it in the past and it's nice as you listen the community. Same things about the no lag on third party application. It seems you have improved it only for Onenote and Evernote that are the most famous and is nice, but we can also active this modality also for other app or we are limited to that three? I'd we can't do you plan to implemented an universal mode like on the Booken Notea in the feature? Thank you for you time and other work.
