Versions 1.x.x of SnappyCam had a linear buffer [1] but I felt it was distracting.

I generally can see the "end" of the circular buffer around the shutter button, so it doesn't seem to be an issue for me. Perhaps I tend to touch it on the lower-right instead of dead-center.

I made an effort to support lefties in the UI (see Advanced Settings), but the buffer doesn't spin the other way just yet. (To be honest, I've had to deprioritise that in favour of other features.)

Are you left handed?

[1] Yes, that's me jumping near the GG bridge. I'm quite good at it now, as you can imagine: http://a3.mzstatic.com/us/r1000/085/Purple/v4/c5/06/d5/c506d...
