I think we are getting some things confused.
1) The SFRA is in the aviation database and you don't need ADS-B to see it. As mentioned earlier in this thread, which started out before we had ADS-B, it's an "unknown" airspace. It shows up as orange with ticks, and has no interior shading. I'm no expert on DC's airspace but there is a large ring and a smaller one inside depicted so I think everything you want is there. Unless you turn off UNKNOWN airspaces, you will see this. We do not consider this a TFR because it is not marked as so.
2) If, and only if you have ADS-B, you will also get TFR's. These will show up in red with red shading inside. You have options for these:
A) Turn them off. This will not affect #1 and you will still see the orange outline. You can do this right in SkyView's menus.
B) Edit the file to reduce or even eliminate the shading, change the color, etc. You can turn off the shading and retain the outline if you want. This requires editing a file with a PC. Again, this will not change #1.
A or B will do this for all TFR's. Sorry, but the FAA doesn't transmit anything special for the DC TFR's, they just call them a TFR like all others. Due to that there isn't a perfect path for us to do something special with the DC TFR (and that's what it is to us) without a lot of work. It's on our list, like a thousand (literally) other things.
