Noticed a small area for improvement

When you interact with a menu bar app (for example, clicking on a network monitor to view a live traffic graph or system monitor etc.), HiddenBar still auto-hides everything once the timer expires — even if the app's popup window is still active. This disrupts the workflow, as the window loses focus and disappears while it's still in use.

It would be great if HiddenBar could detect active popups associated with menu items and delay hiding until the user clicks elsewhere (such as the desktop or another app). Another idea could be to introduce a "stay visible" mode, or even an optional "avoid hiding" toggle for individual icons — allowing popups to remain open even after losing focus. (I know it's possible to move icons to the "always visible" section, but that's not ideal for dynamic tools like monitors.)

Overall, HiddenBar is a wonderful and highly recommended app — and a small improvement like this would make it even better!
