Thanks Andres for the contribution. Hopefully Anselm will get the time to review and merge in your code.
Just wanted to quickly mention that https://github.com/scklss/slock/commits/master is now https://github.com/suckless/slock/commits/master Unfortunately github don't have any mechanisms to move/redirect your issues to the new repo. So I hope you don't mind recloning too much. I've asked github admins to kill https://github.com/scklss entirely except for a redirect notice. Greetings from Berlin,
