Personally, I'd like a nice GUI to pick and squash commits with new commit messages against them on creating a pull request. I don't enjoy using the CLI for this, and it would be nice to thread thoughts on the solution into the commits themselves rather than explaining solely in the PR description.
I second this, also I'd like to see an overview of the (files with) merge conflicts if any instead of a message saying the PR can't be merged. Fixing the merge conflicts might be another thing in the web interface would be cool but I guess I'll stick to the CLI for this.
