Parts you would like to see?

I would like to see more lego slopes without the lip on them that makes it look like a shingled roof when stacked up.
and no rounded corners because when they are stacked up they need to look smooth.

The modulex slopes do just that but are not lego scale, but do have pointy corners. which is good.
Maybe a 2x1 slope that is 2 plates high then a 2x1 slope that is 1 brick high.

While cool, it’ll prolly never happen. LEGO is designed for kids fingers. Similarly to the addition of the tile groove, the rounded corners will never go away.
