Minecraft has been many years without adding new mechanics before you could only jump, hit, walka andrun but now with the new 1.13 has added the new mechanics of swimming, well if Mojang can add this mechanics that costs him to add one to sit, It is a necessity in Minecraft and many games already have it and Minecraft needs it, servers like Minesy have this mechanics if they have it that costs Minecraft to sit on stairs or tiles then please sign this request for Mojang to consider request, thank you.
