Make existing glass blocks tintable colors/opaque
Perhaps with exisitng glass blocks that are in the game (curved, sloped, flat panels) they can have a feature similar to LCD controls where you can adjust the glass color, amount of transparency/opaque, without effecting the window frame color that is typically painted with the paint tool. It would be a nice feature to have some more color with windows, without sacrificing very much coding, preformance, or time. Something where you can approach a window pane, right click it to have a menu appear to adjust the color. Real world applications do exist with "Smart Tint" windows, and automatic tinting glass eyewear, this would be allowing tinting, and color choice.
Certainly consider the use of visable light through custom glass settings, as a means to accent the mood of a base, or the appearance of vehicles. Ask the community, but I think they would use this if it was made available not as a mod, but as part of the main game. thank you for reading my proposal.
