Is your feature request related to a problem? Please describe.
I'd like to have more freedom to build nice-looking things. Mixing slabs together is the one thing this mod doesn't have (in my opinion).

Describe the solution you'd like
There are two potential solutions I see;

1. Add support for mixing slabs (more difficult)
2. Add the ability to toggle specifically slab placement logic so another mod can take care of it (more messy, but should be a quick patch)

Describe alternatives you've considered
I've tried a number of mods that add mixed slabs (normal and vertical), but the logic of this mod overrides them completely. I also tried searching for a mod that adds vertical stairs but couldn't find one that worked with mixed vertical slabs as well.

2. Add the ability to toggle specifically slab placement logic so another mod can take care of it (more messy, but should be a quick patch)

There is literally a keybind specifically to toggle placement logic.

There is literally a keybind specifically to toggle placement logic.

It also disables vertical stair placement, which is a feature pretty much unique to this mod and the reason I made this issue.

So you re-enable placement with the keybind after you're done placing slabs? I'm not adding individual keybinds for the different placement types.

And if you just want to permanently disable slab placement - there's a config option for that.
