Mouse pointer not 'integrated' in guest window and how to set up host-only network with Winapps?

Hey there peeps,

This is truly a real great modification that i am glad to use;
iv'e been trying to get a host-only network to work with virtual machine manager but with my noob skills i can't get it done or just don't know what i am doing. Can somebody maybe give me a hand how i can setup my host to use the RDP from windows 10 but blocking all internet acces for the guest system.

Another tip / point i wanted to make; i got it to work to make a shortcut for Affinity Designer in Winapps and it works so far, the only thing is that the mouse pointer won't intergrate or 'grab' as it would do in the standard virtual machine manager window when loging in to the guest. Is there maybe a hack / fix or workaround to get the windows-pointers that are used for the different tools in Affinity?

Thanks for the help and greetz,

Rubuntu
