I came here while looking for a solution to larger map tag icons. I was wondering if this concept could be extended to those?
What I want to accomplish, is the ability to place a LARGE (2x or even 8x?) very easy to see icon (alpha to max so it isn't transparent)(maybe a shadow or outline) over different parts of the base where different things are produced. Currently there are 2 ways to do it. Regular map tags scale with zoom, so they always stay the same size on the map view. Icons inserted into the text of the tag will scale to always be the same size on the screen. Both, in my opinion, are too small. Bad eyes, as you said. I end up using both, the tag icon shows up when I am zoomed in far enough to see it, and the text icon for when I am zoomed out further. It results in a cluttered look at both levels.
