Remove Application menu when needed

When there are a lot of icons in the menu bar, some of the leftmost ones can end up being hidden by the current application's left menu. The implementation of a feature such as Bartender 4's '_Remove Application menu when needed_' would solve this.

Here is Bartender's description of the aforementioned function:

> If any revealed items would be hidden by the current application's left menu (when they are being shown), Bartender will remove the application's menu. Due to a limitation in macOS, Bartender's dock icon will be visible while the left menu is removed.

Can this functionality be added to Hidden Bar so that icons don't end up being out of view?
