SurvivalCreativity

The switch between Imaginary Creative and actual survival world is seamless and instant, allowing you to very quickly sketch out a build in creative and actually complete it in survival. Unlike other mods for creative sketches brought to survival, with this one you can actually take advantage of the real terrain around you.

The mod is completely client sided and works in multiplayer servers as well. (So long as the server does not time you out for AFK-ing while in the imaginary realm)

There is also a function for sharing holograms with other players, though if the holograms are large a server side mod would be required. For small builds shares work through the chat without the need for a server mod.

In the imaginary realm you get to control everything in the world, such as time, weather and mobs.

The project is completely open source, and you can contribute with your ideas!
