New tab page dashboards

This cluster consists of browser extensions and web apps that replace the new-tab page with customizable dashboards featuring widgets, shortcuts, tasks, notes, themes, and local data storage. The dated entries before the index start are sparse (one in 2016-12, one in 2025-11, one in 2026-03, two in 2026-05, one in 2026-07), so the cluster's dated history is too thin to read a shape from. Among members with activity signals, multi-row-tabs leads with 241 stars, followed by x-media-grid-restore at 62 stars and tab-out at 51 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
