The airbrush tool has been unwieldy and finicky for a long time now. It was awkward to hold and adjust the paint settings at the same time and painting some objects was hit or miss. This update improves the airbrush in a number of ways. First, it now has a floating base so that you can let go of it without it falling to the ground. Second, the new base is larger which means there is more room for the adjustment inputs, so instead of the tiny knobs on the old one, you now have large levers and dials. I've also improved the surface detection so that you're more likely to paint the section you intended. Finally, I added a mount for the airbrush to the side of the toolbox so that it is always within reach, you can unmount it by grabbing the handles or the body of the compressor and remount it by moving it close to the mount. I also made some performance/usability changes. The list of saved layouts can now be scrolled if you fill up the first page of saves. A slide will appear below them that works the same as in the inventory drawers. Hints will now go away if you ignore them for 2 minutes. They will reappear each time you start the game until you either hide them (button inside the toolbox lid) or go through all of them. There was potential for performance issues with the city streetlights so I turned their lights off by default. They can be toggled on and off by pointing and tapping the top of the light.
Finally, I added a placeable crossing semaphore that lowers and raises when railcars path through its triggers. The triggers can by moved independently of the semaphore allowing you to extend the trigger range. They can also be snapped by clicking the touchpad while holding one. There are still some issues with them, one being if you save a layout with a railcar in the middle of a semaphore and the car crosses a trigger, the semaphore will get stuck. List of changes:

• Added initial Linux support (not official until I work out all the issues)
• Fixed the save camera always rendering
• Made save list scrollable
• Remodeled the airbrush and improved its interface
• Fixed painting some surfaces being almost impossible (city building walls)
• Fixed manually ejecting from loco not turning off ride smoothing for that loco
• Auto disable hints after being ignored for two minutes
• Fixed bug where hand wiggle animation could cause fingers to bend too far forwards of backwards
• Fixed extinguisher foam stuttering
• Made streetlight lights toggleable
• Fixed missing collider on large diesel loco causeing it to freak out
• Added dynamic crossing semaphore
• Fixed not being able to slam the car horn with the palm of you hand (previosuly had to be poked)
