RocketLauncherUI Integration OR Added Feature Support

[AHandheldFan]

Hi. I love your work and I love Pegasus-FE. Just wondering if you could implement or are planning to implement features such as 'Hide Desktop and Taskbar', Set Launch/Exit Delays, Not To Wait for Steam Exit to Return to Pegasus, or similar options that RocketLauncherUI has relating to these. GameEx has similar options too.

Also a feature to display non-installed Steam games (to make it easier to install from the one UI).

Lastly, the ability to Hibernate or Sleep/Suspend PC directly from the menu (alongside exit, restart and shutdown).

Platform: Windows/PC

Fairly complicated reasoning about what should occur in https://gitlab.common-lisp.net/cmucl/cmucl/-/issues/196, for which there doesn't appear to be a clear consensus.
