This has always bugged me but how about making the "sortie type" (ie, Fighter vs. Attack) auto-select based on loadout. When you add the first bomb/rocket it selects "attack", if you only have drop tanks then it assumes "fighter". Leave the buttons in the hanger so a person could over-ride if they really feel the need.
Second, give us two gun convergence settings for aircraft that are fighter/attack capable. I like to strafe and my convergence preferences when attacking are different than when working fighters. Connect it to the sortie type so when I load that first bomb my sortie type goes to Attack and my Convergence goes to setting #2. Again, the over-ride would allow you to mix and match if you so desire. If you always use the same convergence, just set them the same or don't set a second one.
