1. camera
I'd really appreciate an alternative camera behaviour where it only moves parallel to the ground when using wasd, no matter where you are looking using your mouse.
An easy to implement but useful setting would be some extra keys for up and down (eg. q and e) for both the traditional and the alternative camera settings.
I support the following ideas already mentioned in other threads:

2. braces
Braces are too strong in some situations. They should withstand almost all pulling forces but not much pushing or bending.
Additionally, they should only have a swivel bearing, it's ridiculous that a brace alone can withstand more bending than a wooden block in the same place:


3. Sometimes objects gain too much vertical momentum, eg. people jumping down a cliff and bouncing higher than the original cliff which is against the law of conservation of energy.

4. To me, cogs will only get other use than for synchronization purposes if they are available in different sizes so that they can transform power. Everything else I would use them for is already possible with the steering block.

5. some responses to other threads
Please don't include stronger cannons or at least don't make them accessible without penalties. I want to be forced to build my own creations to get more power.
I share the following wishes:
