delete me! I am awful at the github-PR version of simon says! i was tricked into coming here! |

Why do you even open up the pull requests? Usually you have to do several clicks to open one. Are you using some automation? |

When you are in a fork and are opening a PR from a branch in that fork, the default base is the default branch in the upstream repo, not the default branch of the fork. You have to remember to change the repo every time. I wish there was a way to change that default. |
