I have did a fast view, I already got some feedback
It would be nice to have the local kvm password kept saved, similar how the GL-iNet app is for routers.
If that is a security issue, I could think of a oauth approach many apps use this type implementation where a user only have to sign in once and it generates a oauth token, this 'open password' will then solely being used for service usage but cannot change things like passwords, if another device is detected expire the oauth password and ask again for password login.
it would be nice if the virtual keyboard has sticky behaviour like for linux ctrl+x or ctrl+a+d.
For the first question, can you provide your iPhone model and system version? Have you enabled AssistiveTouch in iOS Settings? And the mic feature is already in development.
I am using it on the iPad for local access and it is great. One improvement would be a way to override the resolution to something more native. My iPad Pro is a 4:3 ratio. I have BetterDisplay on the Macbook Pro but I cant figure out a way to make Comet be in 4:3. It is a lot of empty space wasted
