I suggest to add a feature which Sony DPT-S1 had: workspaces.
The workspaces enable user to open a set of document ans group them for easy retrieval at later time.
I think it could be very useful.
For example, I’m a student and I open 4 pdfs to study for a subject. Then I switch to another subject and now I have to close all pdf and open the others I need. With workspace all will become simple.
Hello, thank you for your kind suggestions! We will forward this to our relative colleagues to follow up.
