Get motivated to do something worth remembering*** This extension is in very early development and its features are very limited at the moment ***
This Chrome Extension is a tool to help you stop wasting time on distracting sites. It allows a user-configurable time on time wasting sites (right now only URLs containing 'reddit'), then will give you a notification to tell you to get back to work.
If you choose, this extension can also block the distracting sites for a certain amount of time if you exceed the time allowed.
