Detect whether an app has a menu bar icon

[wdhwg001]

Hi,

As I realised it might be a bit complex to manually blacklist all apps that can run on background with menu icons, would it be possible to automatically detect them and prevent them from accidentally closing?

Thanks!

I think this should already work most of the time. Have you tried it?

Goodbye does not close apps that have LSUIElement set to true. Generally, apps set this when they should not appear in the Dock.

Explicitly checking for a menu bar icon is a clever idea though, as an extra precaution. I don't personally know how to do that, but my Objective C knowledge is minimal.
