Allow an app for more than just 6 hours?

[zdat]

Would be nice to allow an application for more than 6 hours.

Would love an option for "until restart" (or logoff) where during/after a restart/log off, an application's access is reverted.

Failing that; 12 hours, or a custom duration would be nice.

Custom duration that can be set by the user would be nice
