The new filter picker is a pain in terms of usability, but only because I need to click "Add" then "Save" when adding a new basic filter.
I constantly find myself clicking "Save" before "Add" which means I need to go back in and reselect all of the fields I added. If I checked the box, it means I want the filter, so why make me click Add?
In short, please remove the need to click the Add button in Basic filtering
We have made an update and it is no longer necessary to click Add when adding a filter. Now if filters are selected and Save is clicked, the filters will be added.
The Add button is still shown, since in many cases you may want to add more filters from a different record type. Clicking Add allows you to do this without having to close and reopen the filter modal.
We also recently shipped new inline filters that can help you add one filter at a time quickly. That may work better for your use case. Learn more here: https://blog.aha.io/a-faster-way-to-filter-roadmaps-and-reports/
