I tried a couple of times to do this the right way (branch in my own repo and PR from there), but this is the closest I could get to work (branch in oF main repo). I'll delete the branch after,
Sorry about this. Feel free to kick me off from admin privileges from oF repo

Haha!!
All good @elliotwoods - I often struggle to get a clean PR.

My current approach to avoid all the merge commits is simply clone a fresh repo and do the changes there.
Then delete. :)
Not efficient but probably saves me time in the end.
