Default Simpicity?

Well I guess "simple"means different things to different people! To some it means having many functions on the stick for flying, but to me it's keeping the installation simple, reliable, and safe from inadvertent actuation.

Something the OP might like to consider, that nobody seems to mention, is that high power functions such as the boost pump and flaps must be operated via a relay since the small stick switches can't handle the loads required. This adds complexity, weight and cost for little gain. Remember "Simplicate and add lightness!'

Also, these planes have sticks, and you can only hold a stick with one hand. What is the other hand doing? If it is on the throttle, then why not place other important switches so they can be reached with your hand on the throttle? way simpler if you ask me!

Well one consideration for that would be removing your eyes from "outside" to "inside", even for the split second that it would require. Close formation flight, or an IFR approach to minimums, or in the flare feeling for the runway, come to mind as times when you would really rather not do that.

Now granted, the number of critical items you might need then is pretty small - but the point remains. There are some phases of flight (short though they may be) when you really don't need your attention/eyesight diverted.

One more vote for KISS.
I chose no grip not even a foam thingie because I fly most of the time with my wrist on my knee, and two or three fingers holding the stick several inches down.

Other than the PTT on the top I put an A/P disconnect switch down on the side.
