Apologies if it's covered on page 2, it's sleepy time and I skipped it - but wanted to add...
My SL1/100D is set up for back-button focusing!
Have a rummage through the custom features, I don't recall the steps but it's in there
Also, 35/2, 50/1.8 (mk 1) and 100/2 are ace wee EF, fast primes on this little guy! (They look super-cool on it, too..) I've never been interested in the pancake, seems no better than shooting a fast compact from what I've seen, IMO.
Also, also - if people try supporting this camera primarily with their LEFT hand under its body/lens barrel, like someone who knows how to hold a camera, and just use your finger/thumb tips of your right hand to hit the dials and buttons there's no real problem with its handling
Also, also, also... I think I prefer framing with tiny viewfinders - and I primarily shoot a 5D3!
