Save snippets without worrying about where they belong. When you have time, review your Inbox and move the snippets to their appropriate topics.
Start by switching to Inbox Topic on your extension
When you finish saving snippets and you are ready to do a review, go to you Dashboard. There, in the top left corner of the side menu, you will find the Inbox Topic.
From there you can Drag&Drop snippets to any Topic you like.
