Hi Jawahar,
I agree with you and that would also limit the options that users need to be familiar with.
But the two options which you mentioned are simply navigation elements. The Document View is for users to set bookmarks and navigate to them. The New Story is to navigate to stories which are assigned to them.
The modify options in Lumira open up the whole Visualize and Compose phase similar to the Desktop. So the users are still hidden from a whole range of functionalities to edit.
Please let me know if there are any questions or comments.
Thank you,
Varun Anand
