I was greeted today with a new look for JIRA which has halted all progress for my company. Moving all the custom fields to the right has made it impossible for us to track our projects and view large amounts of data - entered into custom fields - effectively. The loss of the tabs has forces all our custom fields into one long row. With some screens, we have over 50 custom fields which makes this right side very lengthy!
PLEASE ATLASSIAN - rethink this design. This is not improving efficiency for those who utilize custom fields and multiple tabs within a JIRA screen.
