I was on a branch, made a commit to it. I also had some local changes in other files. When I run git-webkit pr command, it automatically tried to create another commit from local changes. This might be unexpected for users, especially when they explicitly committed what they wanted to commit/push. Coupled with the fact that git-webkit pr doesn't show any preview before creating the PR, this might not be a good idea.

git-webkit pr shouldn't try to automatically commit local changes when user is on a branch and there is already a commit by the user on that branch. Either errroring out or asking the user if he/she wants to create a commit from local changes is better.
