I am still on 2.15, recently saw that they added some straight line sketch tools, should I update or stay on 2.15? Seems to be the last reliable software version without any stupid glitches.
Am I right that current software version now has the notebooks not as pages but one big long scroll down? That is a deal-breaker for me.
I also noticed the NOT SUBSCRIBED. I hesitated for over 6 months from my purchase date, then I decided to try it. And I do love being able to send from PC to TABLET some PDF that I occasional use for reference (I don't use it as a reader, but its nice.
Also check out the GOOGLE docs/sheets integration. I occasion make some little SHEETS on google, and push it to my tablet where I make some markups on it for the next time I'm there to update it.
