I subscribe to notifications of many orgs and repos with my GitHub account. The work portion of those I don't want to really see in evenings, weekends or during vacation, vice versa some of the OSS and personal projects I don't want to see by default during a work day.
The options of this extension contain 2 textareas that accept strings for GitHub organisations or repositories (one per line). When visiting github.com/notifications the extension compares the entries of the first list with the headlines of the notification tables, and hides them if a match is found. The entries from the second table then allow you to unhide some of these tables again (which e.g. lets you hide a complete org, then just show some specific repositories of it).
