1. The ability to copy and paste a section of track, and be placeable as any other ride with ctrl/shift for height placement.
2. Ability to save track designs without stats, for merged track rides
3. Ability to see Money tab on stalls when "No Money" is enabled. (particularly useful if you're trying to see what a stall sells).
4. View Improvements:
Ability to Hide Water
Ability to lock the view, so closing windows doesn't change it
Ability to lock cut away view window (so shift-backspace doesn't close it)
Hotkey and/or menu item to remove all views
Ability to move past edge of map more when zoomed in all the way. (For maps that have tall terrain).
Sorry if any of these have already been suggested! Just have been compiling a small list of things that I would like to see implemented. There is one or two things that have escaped my mind at the present moment, so I may or may not add to the list!
