Allow access to machine settings while machine is running

[Stephan Müller]

The machines I use are running or state-saved most of the time, so I can spare the time restarting it when I need them. I only restart them when I need to (eg. software updates) and never shut them down. This makes it pretty hard to change its settings; since I cant even look at the possible options without shutting it down first (and sometimes even have to turn it on without a change if the desired options aren't available at all).

Since I understand the need of restarting the machine for the changes to come into effect, I propose the possibility to change the settings at any time for them to get applied the next time the machine shuts down or restarts. In the GUI, the changed settings could be marked by some kind of "restart required" symbol and a reset button to the actual current state would also be convenient.

This feature could be used for example if someone notices the need of more RAM while compiling a big project, without interrupting the compilation. Or to activate a new feature in VirtualBox. So one can make the changes when their need is noticed, finish the current work and restart anytime later when all processes are finished.
