It would be great if the application/branch selector could be resized, or lacking that, the columns within (Branch Line and Message in particular as shown below). Oftentimes the names and commit messages of a branch are longer than the space given, so they can't be read. This is particularly a problem when you have several branches that have the same characters up to a certain point before diverging, because you can't tell which one you're selecting.
