I have personally found using schematica in its layer-by layer mode to be one of the greatest tools available to me as a Minecrafter. However, I often misplaced or otherwise mess up when attempting to place a block, and accidentally break something on the layers below me. However, since the layer-by-layer by layer mode only shows a single layer at once, and the all blocks mode shows far too many above the current working layer, I have to individually click through each of the previous layers in order to figure out what I messed up.

It would extremely useful, not only for this but for other use cases to be able to have a top-down mode for layer-by-layer, where every layer under the current working layer is also displayed, highlighted, and catalogued in the material list. This would ensure that you can check all previously made layers without having to deal with the visual clutter of turning on ALL mode and having tons of unbuilt layers also displayed.

Anyways, thank you Lunatrius for this amazing mod and all you've done to support it.

Top-down is not really the proper term for this. You'd basically want the selected layer and everything bellow to be rendered, correct?

I would love this feature as well! It would make building and checking as you go much easier on complex schematics.

That's what it sounds like to me - in addition to ALL and Layers there'd be a All below mode, that works as described.

I've submitted a pull request (#289) that adds this.

@Lunatrius Yeah, I guess you're right. Pokechu's ALL BELOW sounds better.
