A minimal Chrome extension that automatically groups new tabs with the tab that opened them, like dia browser.
When you open a link in a new tab (Ctrl+Click, right-click → "Open in new tab", target="_blank", etc.), the new tab is automatically placed in the same tab group as the opener. If the opener isn't in a group yet, a new group is created for both.

- Only works when Chrome knows the opener relationship (
openerTabIdmust be set). Tabs opened from the address bar or the new tab page are not affected. - Pinned tabs cannot be grouped and are always skipped.
- Cross-window tab opening is not supported by Chrome's API.
