They can pick up there properties but there is no concept of "abandoned" otherwise. Most people leave them there and then the area is protected forever unless I have cause to move it.
Since I never gave anyone a time limit I have trouble removing properties just because someone hasn't been on in a while.
I don't plan to add any blocks for diagonal docks, really. To make enough blocks it would take up 8 slots or more for relatively little gain. I'm more likely to add multi-use shapes than such "single use" ones.
Okay... here's a question.
You have played Minecraft, that is a given. (OOPS, I SAID IT! lol) You remember when they first came out with multiple types of slabs? My first instinct was to go make a new world, cut down a tree, dig up some cobble, and make both types of slabs. I placed the first on the ground, then the other on top... but it was hovering over it, as only one block can occupy a space at one time (Including the AirBlock, WaterBlock, TallGrass... ETC).
My question is, would it be too hard to make it so you could, say, place one slab of one block, and another of another block on the other so they occupy the same spot (Without having to make them objects, as that can make placing take a LOT longer, and the texture is... smaller)?
I know that question is kind of boring and not a very cool thing to add... but it can make constructions WAAAY better. Just adding a single extra corner block can change the look of an entire city to look COMPLETELY different.
Also: I don't think this counts, as water isn't going to be a block in the future... but it would also help for water being able to occupy a corner block that is touching water (Though, you might not have to do this as if water isn't a block, it would actually just flow into the opening).
