Random Tips
ill post all the tips i know but if you use them please give credit.
1. A way of filling layer connect.
Draw loads of lines closed together
2. Speed up on a nose hang.
draw 1 red line whilst on a nose hang and he should come up and flip, now hold shift and draw that line again (with that line still there) so there both speeding up the same way but one upside down. done!
3. little tip with layer connect.
you might know this but layer connect
1. only works with the layer behind (or Maybe infront) of that layer and
2. you dont have to snap to make layer connect work.
4.make things look better than they are
chose a colour same as the background and make a stall (it Can be just a line rider staying still)
chose a decoration line and colour it not back ground and draw it over a bit of the blue line stall and it will look like he's/she's stoping on a small line.
5. how to save clip art
draw your clip art and select it with the selection tool (duh). with it still selected click the stamp / clip art, use the arrows to go to your profile (or whatever you want to save it to) name it and click save
hope this helps 
Occasionally, I'll post some random tips here to help out with track creation, and to help those unfamiliar with the game and its interface. Many of you will likely already know a lot of these things, but they may be useful for those who don't
Feel free to add your own tips! I'll edit them into this post

- You can start out in night mode without using a trigger by going to map properties (from the Esc button options menu) and selecting the night icon and checking the checkbox
