As requested by Muqthar:
We should have a way to navigate the documents one by one to next from its page itself. For example QTN#1 to QTN#2,QTN#3 and so on. Right now, overtime we have to go back to quotation list again and select the next one.
It will be very useful and much time-saving. +1
Maybe something like this

Next - Previous
First - last
Cancel
Search
That would be really great.
This is great feature
If you are on a filtered list, the user will expect to go to the next filtered item as per the list view
Yes, that option too. I must suggest better filter options. i think it is more intuitive to be in POP UP window. I will suggest to change sort type field in search by to be select field (ID, Customer,...), and on the right side search field like it is now. When user choose sort type to get the same by default when next time start to search. I will make some mock up later

This is especially true for the Email Inbox feature. It feels awkward to go, email to Communications list and back to next email.
Really really useful
Useful and important, it gives more power for ERPNext in manipulating the data.
