The app experience could be considerably improved by adding shortcuts to the following categories of tasks: navigation, annotation.
Things I can think of right now in each category:
Please add the standard shortcuts, and make it easy to annotate in various ways with just the keyboard. That is very important
Well designed keyboard shortcuts are absolutely essential, to aid a fast workflow. Please give this your highest priority.
I agree, simple thinks like copy+paste (cmd+c and cmd+v) in all textfields as search and also metadata should be supported (also within the pdf).
getting really great with each update!
