Graphic Designer here
Love the iOS app. I think others are right with you should be treating this software as a windows application like Brightroom or Word instead of an Internet extension.
-As a beta, I was expecting more being able to log into my account like, being able to see what I have already created on iOS since I paid the fee. Even if all the features arent there just being able to reference them would be nice and just a little pop up window of "hey, not all features of this document will be available with this version and editing will be limited" or "this is a view only notebook" would have been enough.
-No stickers sucks. As a graphic designer I make my own "bullet journal" layouts and not being able to create stickers or add svg files takes away a lot from this beta. I am sure it is a work in progress but I hope it is an update that you add soon.
-Not being able to edit normal pdf's for professional use on Windows is also a turn off. I pay for the iOS version, if I am doing work on my Laptop I don't want to have to upload and export a pdf to my ipad just to edit it and send it off. PDF editors are expensive, that's why I choose you guys.
That is all I have for meow, but overall love the concept and hope to see more soon.
