someone has probably already said this, but i really want to be able to place slabs vertically! i just think it would create much more possibilities for design and decoration haha
i also wish theyd add more stuff to the nether maybe. quartz is cool, and glowstone is very useful, but i want more ores, or maybe even plants that only grow in the nether (like ive seen in some mods)
it could also be neat if they added a version of glass without the streaks on it (though this is only a problem with the vanilla resource pack). i just think itd be a simple fix, maybe having to smelt the streaky glass again, or craft it into clearer glass. i dunno!
thats all i can think of at the moment :<>
