I’m sure others have mentioned this in some regard. I’m personally tired of farming and grinding for supplies only to tear it all down when it doesn’t work. An app won’t work, as the in-game terrain is where I want to build.
All I want is a simple square and wedge base planner. Please let me lay out the floor plan. All that is needed/required is an empty placeholder that can be upgraded later with any applicable tile e.g. Ghost-stone… looks like sandstone, but bluish and you can walk through it (no collision).
So you open your inventory and in the crafting section you have two new recipes: Ghost-stone Foundation and Ghost-stone Wedge Foundation. Once you have finished planning, build and (re)place your tiles like you normally would except they will snap into the plan; replacing the Ghost-stone. Simple yeah?
The idea could be expanded for some (all?) furniture items including a Ghost-Map Room and the various wheels of friendship, uh pain and animal pens! This would be beneficial for the big items so you know how they will fit.
