Once you navigate through the tree to open a requirement in Zephyr Ent, breadcrumbs appear on the top of the screen. But these breadcrumbs do not contain hyperlinks to navigate back through the breadcrumb trail.
The only way I've found to get back to the main requirements tree is to click the back button, which takes you to the most recent folder. Then use the main folder structure to move navigate to other folders as desired.
Adding a hyperlink to each section of the breadcrumbs would allow for much more efficient navigation to the desired destination folder.
Example use case: After looking at requirement 2532, I want to return directly to the main sd_demo_zephyr_release0 folder.
