As an IT Infrastructure Manager administering PRTG, I want a global 'Collapse All' / 'Expand All' button at the Root level of the device tree, so that I can instantly get a clean, high-level overview of all devices without having to manually collapse each one individually — especially when onboarding new users or verifying permission configurations via a test account.

Whenever i give a user access to our PRTG backend the first time they login they always see all the devices with the sensors unfolded. Sometimes i also have to test myself to see if the permissions to certain devices i configured are working, so i use my test-account and login.. then i always have to "fold" (not the right word) the devices in order to see a proper overview. If it is 1-10 devices then its not that big of a deal, but most of the time it is 100+ devices. So it would be nice to have a "+" and "-" button at the top of "Root" that makes it possible to collapse every device so you have a nice overview.
