So, I tested a bit the path system. It is powerfull, similar to Planet Coaster 2 system. So, I got some suggestions and a fix wish:

To fix:
- When path is drawn in different heights, there's no texture under it. Suggestion to fix: use selected Curb Style texture under it. If it's off, use a default curb texture.

Improvements:
- Hold Shift to adjust height: when you hold shift, you can adjust path cursor/brush height.
- At the cursor/brush, add two lines crossing to make easy to find where squared style begins.
- If curb is selected, a circle (slightly smaller than brush size) will appear in brush, indicating curb size and location.

Future Improvements:
- Railings: Toggle on/off Railings on curbs (steel railings, wooden railings, concrete parapet, glass parapet)
- Auto supports when paths are at different heights, or crossing different heights terrain (support types: center circular, center squared, wooden bridge, steel bridge, concrete bridge, enclosed concrete bridge [curbs all the way down])
