Feature description

I would like to suggest a feature where molly could give the user control of what conversations can be shared to a linked device. If the user only wants 1 or 2 conversations allowed to be shared on a linked device for example but not other conversations that are sensitive. The reason being, if you have for example a pixel with GrapheneOS, knowing that this device is the more secure device, for example full verified boot etc.

Where malware can not survive a reboot, but you share this molly account with your laptop or other device where you can not guarantee the integrity of the operating system, and the exploit mitigations are not as strong as on the pixel device.

This makes linking your device to a less secure device a problem. Would adding a feature that gives the user more granular control of conversations shared to the link device help?
