I absolutely love your service and will definitely renew it considering my one-year license is close to expiry.

Any reason why you don't use a PPA or something to auto-release updates? I've postponed an update quite a few times because the friction of going to your website, downloading it, and then upgrading the package is just a bit too much in certain situations.

Other than that my only gripe with the app is that I can't close it from the app indicator, but have to re-open it, click on the settings, and then choose "quit app".
