Unfortunately, Github's search doesn't support OR operator over labels (or at least I don't know how), so here a list ordered by number of open issues at the moment of writing:
- easy
- beginner
- [Good First Bug](https://github.com/search?utf8=✓&type=Issues&q=state%3Aopen+label%3A"Good First Bug")
- starter
- E-easy
- newbie
- [easy fix](https://github.com/search?utf8=✓&type=Issues&q=state%3Aopen+label%3A"easy fix")
- easy-fix
- [beginner friendly](https://github.com/search?utf8=✓&type=Issues&q=state%3Aopen+label%3A"beginner friendly")
