It definitely needs a Mac Version to sync up with and being able to do at least text and PDF based stuff on it. Also, when selecting text with the marker/excerption tool, it would be great if I could move the beginning and the end of the marker. I often miss the beginning of the word by one or two letters or later see that I would have wanted to mark one more word and it‘s cumbersome to delete everything just because of a little mistake. Would make it easier to work with. Overall still a great tool that definitely deserves more attention and love!
