[Dev] World map transparency

[HunkaMunka]

While the existing world map is already an overlay, I must concur with the OP and say that an option to adjust the trasnparency would be appreciated.

Whether it's ambient lighting, my monitor settings or in-game settings that make the difference, I'd still like to be able to adjust the transparency.

I don't always play at the same time of day or under the same conditions, so instead of having to adjust my room/monitor/weather to make my world map transparency more noticable, I'd rather just be able to adjust my map.
