Roof Pieces Should Be Contextual (Like Slabs)

[EndlessOats]

You can't put roof bottoms on the top half of blocks. They're locked to being "bottom slab". They should be able to be used to create half grades

Roof angles are sometimes too sharp and the roof bottom is the perfect solution, except that it's locked to the bottom half of the block and so cannot be staggered to create shallower angles. Please fix, I am very irate after designing a shed around that concept and now I have to start over. Thanks!
