In MS I can reduce the amount of icons showing while I am creating a route by selecting Map Detail Setting from Lowest to Highest.
I believe while searching around Basecamp I thought I found a place to turn off certain icons. When I open Basecamp I see a lot of plane icons for airports. I don't use the airports and would like to turn them off but would like to turn them back on incase I need to find one.
The attachment is an example.

BTW is there a way to post a photo from my computer without having to load it on an internet website?
