PaperCSS was originally made to be something different than the typical mODerN STylEs and clean pages found in every other CSS framework.
Todoist Time is a Chrome Extension that allows a user to add time estimates to Todoist tasks. Just use Todoist’s built in tag feature
@t30m to add a task that will take 30 minutes to complete. The summary of time estimates is at the top of every page too!
