Describe the improvement

Currently when unigetui is updating a bunch of packages and/or installing some packages it shows you the progress with a number next to the operation and you can scroll to the bottom to see how many operations are left.
It would be great if this number would also be shown at the top, see example screenshot where I drew 23 as an example number of packages being updated/installed:

Describe how this improvement could help users

Would show users at a glance how many operations are queued up :)
