Onemark – Bookmark & Tab Manager Sidebar

Bookmark manager and Arc-style side panel: pinned sites, tabs, bookmarks, downloads in one place, plus optional cross-profile sync.

Onemark is a bookmark manager and an Arc-style side panel for Chrome: your pinned sites, open tabs and bookmarks live in one panel, with a full manager page for the big cleanups. WHAT YOU GET • Side panel (Cmd+Shift+K / Ctrl+Shift+K): pinned grid on top, open tabs and bookmarks below. Drag to pin, drag to reorder, multi-select with Cmd/Shift. • New tab page: every new tab opens on your shortcuts, frequently visited sites and bookmarks bar, watched over by a calico cat that follows your cursor and smiles when you pet it. No search box, no feed, no ads. • Tabs that know their bookmark: when a tab drifts away from its saved URL, one click on the favicon takes it home. Closing a saved tab keeps the bookmark; opening it again picks up the same tab. • Automatic tab archive: sweep idle tabs into dated folders instead of losing them, restore them any time. • Manager page: folder tree plus smart views — All, Recent, Cross-profile and Downloads — for search-and-destroy cleanup sessions. • Downloads: recent downloads right in the panel and a full downloads view in the manager. • Search everything from one box. Note: the interface is available in English, Japanese and Traditional Chinese. YOUR DATA STAYS YOURS • No server, no account, no analytics. Everything runs locally in your browser. • Cross-profile sync is optional and writes to a Gist under your own GitHub account, with a token you create. Use a secret Gist: secret Gists are unlisted, but anyone with the link can read one. Onemark never changes a Gist's visibility, but it does check it: once when you save the settings, and again on every sync. A Gist that is turned public later stops syncing. • We never see your data — there is nothing on our side to see it with.
