i have some suggestions for this mod:

• let slabs can mixed double slabs together like mod Double Slabs (https://www.curseforge.com/minecraft/mc-mods/double-slabs)
• can place torch on these slabs.(although on vertical slabs)
• more fence like mod Custom Fence (https://www.curseforge.com/minecraft/mc-mods/customfence
• can add custom images or gifs in game.
• a computer can browse Internet
• some toilet's furniture like washbasin and shower. Also compatible create's or mekanism's fluid system.

None of these things fit the vision I have for this mod.
