Hello

Add a glass pane that can connect to stairs so it done have the little hole in it would be a great one to have in the mod for builders.

Stairs are a bit problematic. Since they are a full block, there is no direct way for a glass pane to conform with the profile in the same block space. This is why there are not a lot of glass pane on stair mods. Some of the ways I have looked at accommodating this are:

1. Make every combination of stair/glass pane a two tall multiblock. This requires a lot of variations, especially if I want to support modded stairs and breaks most stair compatibility.
2. Make a "Stair Pane" that goes above the stair block and draws a phantom image below the pane overlaying the stairs. This is kind of hacky and prone to failure.
3. Replace stairs with a glass pane compatible version with functionality kind of like the way flower pots can hold a flower. I have resisted replacing any vanilla blocks because that can lead to a lot of incompatibility with other mods.
4. Add a new stair variant in all vanilla woods/stone that is pane compatible. This would be the way I would go if/when I can get some time to think more about this.

Thanks for taking the time to post a suggestion :)
