And it's taken an awful long time too! Yes, it makes the game a tad more complex to play, but the results are much more satisfying! Before, if you wanted to edit a part of the coaster near the beginning, you would need to backspace and delete all the coaster that comes in front of it. That was not fun. Not at all. You'd have to ruin a lot of work. Now you can just click the segment you want to edit, drag it around with the mouse, and drop it where you want!
Each track segment node has two handles. They control the angle that the track enters and exits that node. The video below will help explain this better than words can!
If you right click a segment of track, you'll get a few quick options to help you out along the way:
Smooth
Will try to predict the track shape you are trying to make, and smooth out the track!
Straight
Will make the section of track you're working with perfectly straight! This is almost impossible to do manually, unless you turn on snap-to-grid.
Split
Create a brand new segment of track. Out of nowhere! This is useful if you want to add a bit of extra coaster that you didn't think of before!
Advanced
This will open a new panel which allows you to edit the track by actually entering in custom coordinates and values. Very exciting, but most people won't really need this!
Delete
Every coaster segments worst nightmare! It effectively does the opposite of Split, and removes a track segment node.
Brilliant!
Only downside is that the level editing process seems to take twice as much time now. Maybe you could set a key to reposition the mouse cursor over the "new rail-node box".
Spitznagl:
The editing process does take longer , but it has the advantage that you can actually go back to the beginning of the coaster and just edit it at any time you want

There are tonnes of examples on the internet, even some on TDC!
