Legacy Jira had a primary option called Issues that could be filtered based on selections (e.g., fix version or status or type). I used it all the time. Where is it or its new equivalent? I tried filters on list, but its almost unusable. If this is 'it', how can I learn how to use this currently problematic feature? So far 
on new Ux, but its mostly looking for legacy features that were part of my every day.
