This would be better for newcomers. Instead that all of the hideouts have the same cash sign, the ones that are not available because of their close locations, should have the red S sign just as flares, so its easier to recognize which hideout is available or not.
Maybe just add a red dollar sign. But I agree it should be marked differently.
Yeah I had the same thought recently. The way I coded it means I have to change a lot to make that work, but should be easy enough to do. I only implemented an argument to 'highlight' one of the markers, not grey/red some out, but I'll do that.
