Suggestion: Optional disactivation of device on exit / Optional Cache disabeling on start

I would like to see an option that, if enabled, will disable the device for secure removing on exit.

There also could be an option, that disables the cache "optimized for performance" on pre windows xp systems.

Both would make hotplugging of the stick more comfortable.

At least there could be some code that closes the PortableApps.com menu, if the stick is removed.
