That's exactly right -- I'd be most happy with an "Inbox" document that collected files, etc. shared in this way, so that I can organize them later on desktop. My main use case is capturing images of blackboards or scanning paper notes with my phone, and wanting to quickly save them to my dynalist so I can do further annotation and organization through the desktop/web app.
I already use an "inbox" folder in a similar way in my dynalist. My mobile use cases are almost always
1) Adding a quick note to the inbox, organizing later on desktop
2) Saving a link to a webpage to my inbox, organizing later on desktop
3) [ideally] Uploading an image to my inbox, organizing later on desktop
4) Searching in a document to refer to a specific item
Echoing some of the other feedback, while I definitely appreciate having the full interface available in the mobile app, it's very rare that it's worth the trouble for me to use it instead of waiting till I'm on the desktop/online app. It would make a huge difference if the app streamlined these 4 simple use cases, which don't involve any type of organizing or moving notes into a simple, fast interface -- and it would really set dynalist apart for me from some other list/note/productivity tools.
Cheers and thanks again!
