The Veras 1.9 Release now includes custom presets. So you can save all the settings including the seed as a preset. The preset is synced with the cloud, and you can access it from any flavor of the app (web app, or desktop clients).
This idea of saving the entire render is still a good idea, as it would additionally save the resolution chose and the render itself. The presets don’t replace this idea, but they helps with retaining setting customization.
