Hey, is there a plan to get a Steam Workshop in the Future aswell?

Can you add a sandbox mode? Some where we can play without a timer?

I can't type 'i' in the game which makes it unplayable.

I am trying to set up a model using the tutorial but the type up asset package links are broken and lead to nothing, does anyone know where I can get the package?

If so, are they available to download? Unity is a clear as mud to me.
