Settings
Many of the options you have used on the main screen are now moved under settings with new versions of Limbo. Under settings you can find some of these options:
Enable Legacy File Manager
This option will enable a custom file manager to choose hdd and iso images. This is provided instead of the standard Android file choosers in cases you have a custom ROM or your stock ROM does not support the new Android Storage Framework. Bear in mind that this feature does not support external storage like SD cards. It also requires full access to your internal storage for which it will request at the first time you use it.
Orientation
This is the orientation that the virtual machine will be displayed. You can lock the orientation if you frequently move your Android device. Keep in mind this is not the orientation for the main screen which will be always be auto rotated.
Always Toolbar
It is helpful sometimes to always show the toolbar if you use it a lot especially if you are on desktop mode and you can spare some extra pixels.
Fullscreen
If you are on an Android device with a small display you might want to get the most out of your Android display and hide the notification bar.
Key Mapper Layout
You can customize how many buttons your key mapper should display. On smaller devices it is better to use a 3x6 grid which should provide with large enough icons to press. Keep in mind the key mapper is helpful for gaming on handheld Android devices but on Desktop will just get in the way of your external mouse.
Prevent Mouse out of Bounds
Virtual machines you have configured with a "usb-tablet" and use a "Touch Screen" mouse mode might show an unexpected behavior where the mouse seems to warp on the other side of the screen. Use this option to limit the mouse movement and prevent this effect. Note that if the virtual machine does not support usb-tablet or does not have the drives installed it will show an invisible wall.
Key Press and Mouse Button click delay
This is a workaround for the virtual machines that does not detecting keyboard and mouse clicks. It is basically an artificial delay in between presses and clicks to allow the event loop detect all events. If you use lower values your changes are that the events might not all be detected.
Enable QMP Server
QMP Server is QEMU's communication means that allows you to do many things like pause and restore the virtual machine state, change the vnc password, and change CD ROM and Floppy disks.
Allow External QMP Connections
If you want to connect to the QMP server from your desktop.
Enable VNC Password
It is highly recommended you add a password to your VNC service. This is because any application on your phone can use the vnc service. You don't have to add a password but your device will notify you before it starts the VNC service.
Allow External VNC Connections
You can allow a computer on the same network to connect to the VNC service. The communication is not encrypted so make sure you trust the network you are using!
Enable Aaudio
Aaudio is a native audio stream that is provided by Android and can give Limbo better performance. This is only available for devices with Android Oreo and above.
