You are quite correct and I have asked QNAP support to tell me their plans for this App to no avail!
I Still have unanswered questions however.
1/ Do you (QNAP) intend to add any of the previous functions to Notes Station 3? i.e. Calandering and Web Clipper?
2/ If not why does te default installation still include the notebooks for the Calendar which I cannot delete?
3/ Will it ever come out of Beta?
4/ Do you have a list of proposed improvements, i.e. some kind of roadmap of intentions for the future of Notes Station?
But got no answers to these questions sadly...however, I was directed to "Try" Notes Station version 2!
All I can suggest is that you also ask for these missing "features" and anyone else who thinks this might be a good idea to do the same. QNAP will only make changes for a large group of users and not, sadly, for individuals in the mist!!
I also asked if they could have PDF documents show inline rather than simply as links to download the document you have presumably already uploaded!! They "said" that this had been put forward to the Dev. tem but...I shall not be holding my breath waiting for that to be implemented
