Hello, thanks for ideas! The editor scene preview of all enviro effects like clouds, volume lighting and fog will be in 2.1.0 with toggles out of the box. So you will have a close to final look while you are working in your scenes. About your other ideas: You can set the order of your weather presets in your zones to also account for more commonly weather there. For example setting the snow or rain presets at top will make them more commonly. Point 3 will be added in 2.1.0 and I will add weather patterns to my list of upcoming features in one of the next updates too.
