The feature-update for the Winter Resort Simulator add-on just got released and includes some of your requested features.

Here’s a list of added features:
- Summer covers added! Summer covers can now be toggled with the "I" key. When active, the functionality of the snowcannon is limited depending on the type (tower, lift, arm).
- Toggleable flashing light! The flashing light can now be toggled with the "P" key. When active, the light is flashing continously, independent of the current state of the snow cannon.
- Toggleable night light! The night light can now be toggled with the "O" key. When activating a snow cannon at night, the light will activate itself too.
- Terrain alignment of mobile snowcannons! By pressing the "G" key, the support legs of the mobile snowcannons position themself so the snowcannon is horizontally aligned. With the "T" key, the support legs move back to their default position.

Some features might not show up at the top left, due to the limit of 6 hints up there. If you are unsure about some keys, check the key bindings in your settings.

Enjoy!
