We have experienced issues with every change to the UI to date. For a company that supplies QA software, this is pretty poor.
Our latest issues revolves around Folders. We cannot see all of the folders in the dropdown on the defect listing screen, nor can we see the full folder list in the dropdown within the defect itself, including the current folder for the defect! Plus, Folde Name, on the listing screen, contains the folder ID instead.
This is making the product virtually unusable for us. I shudder with dread every time I see there is a planned release...
