BTW, is there a way I can get rid of these 'merge remote-tracking branch' commits when I send PRs?

@browner12 it looks like you have a local 5.4 branch and previously did a --no-ff merge of laravel/5.4 into it. You can always use merge --ff-only when merging upstream to your local unmodified branch to prevent merge commits.
And if you still have merge commits in your PR, then you can rebase it onto the remote branch laravel/5.4.

thanks for the info. It looks like this is a common thing with Github desktop users when updating from the origin. It does a merge instead of a rebase. I guess I'll just have to get myself more familiar with the command line git.
