Tips that I learned and are not obvious :
- You can hide the categories or focus on a specific one.
The categories always change when you mouse over or want to build only with flat road ?
Press TAB to hide the categories and right click a folder to focus on it then use the arrows at the left to go back.
- You can turn the blocks other than by right clicking.
Want to make a decor that follow a diagonal line ?
Select free block mode and press numpad + or -.
- You can select any ensemble of block and save it as macroblock.
A lot of sign with support to place ?
Make a macroblock by selecting it with the copy/paste tool and save it with the save icon.
You can also copy/paste/save mediatracker trigger. By example a start block with the gps/text trigger.
- You can stop the sticky behavior.
Too much deco/block in the way and it get stick everywhere ?
Hold shift and be free.
Will complete as I learn.
I wish there was a proper documentation in-game.
