I'm sensing some love for the flags here but in truth they are the sort of thing I prefer to have as an add on. I get eye twitch at the thought of snap off parts and so things like flags tend to be separate. It also means the ships can be.....piratical! if I so choose. 
Oh, HELL yes, we understand, but some 'oles to stick 'em in would keep us quiet.

"Verticals and Horizontals" I'm not sure I know what you mean Mr Beast. Are you referring to undercarriage markings?
Sorry, referring to poles or lines for signals. I suddenly imagined a line of pennants stretched from the sides.
The things that pop up in my mind. Really, no control...
