[Feature Request] Allow to save a configuration

[jtsagata]

It will be nice if it allows saving a given configuration.

Use case

I have 3 monitors. Sometimes, for example, when I watch a movie, I use only one, other times I use the 2. It will be nice if you can save a configuration from the GUI and the use the CLI to select one.

Currently, I use autorandr with some keyboard shortcuts. Plus, if you can run a script, like autorandr do. Use case to switch the monitor to "movie mode" using VCP.
