I hosted a site for classical warfare aea on github pages, and that is free: https://jeff-web-sketch.github.io/ClassicalWarfareAEASite/index.html

I like the idea but would be hard to display icons if there are many different units garrisoned. Also might be confusing if you have icons for training, but also for garrison.. There is also a limitation where it's not possible to display text (or numbers) for the while this feature is in a mod.

@Atrik great job! Would you be able to show the number of passengers on a ship (and on a siege engine) in the same way as well?

Another one (or the same one I pointed out before?) KILLLLL!!!

Now added idle icons for buildings. Also can be toggled independently icons for idle workers.
