We work with tickets all the time and have a custom query that we have as a starting point.
The workflow is usually clicking on a ticket, doing something with it and then returning to the custom query overview.
The issue is that while going into the ticket and then back is easy by just using back in the browser, it's much more of a hassle if you have commented on a ticket or something similar. There is no easy way to get back to the overview. You have to either click back 2-3-4 times or click on the phabticator-logo, then maniphest and then the query..
