With all due respect, trees are the last thing you need to worry about. Let's try harder on getting an update that isn't a jizzy frustrating sim with a crapass undo button, no fear in deleting a track node, a segment straightener that doesn't piss the I Love You! up out of your track, and a way to edit a pump without only making it worse and realizing the undo button doesn't have your back.
1 year and a half of ownership and practice is extensive use, and I am not complaining about the difficulty of the trackwork. The undo button needs to work...
The undo only works if you move a piece of track. It won't redo anything you do to control beziers, won't undo splitting a segment, so you'd have to delete it, which again completely deforms the structure. Doesn't undo deleting a segment completely. Doesn't undo making a segment straight. It only undoes moving a center point, which is vastly frustrating.
