Trello Helper

Hide & highlight Trello lists, filter cards by name or custom field, and chart board stats with pie charts + flow diagram.

Trello Helper — Focus your boards, filter your cards, and see the big picture Trello Helper is a lightweight productivity extension that adds the board controls Trello is missing. Hide the lists you don't need, spotlight the ones you do, filter cards by name or custom field, and turn any board into instant charts — all without leaving the page. Everything runs locally in your browser and saves automatically per board. ★ KEY FEATURES • Hide lists Remove clutter by hiding entire lists from the board. Hidden lists take up no space — the remaining lists snap neatly to the left. Perfect for archiving "Done" columns or focusing on the work that matters today. • Highlight (focus) lists Dim every list except the ones you care about so they stand out at a glance. Choose what to focus by manual selection, by keyword, or by card count (e.g. show only lists with 5 or more cards). A live preview shows how many lists will be focused as you set the rule. • Card filter A one-click Filter button right in the board header. Hide cards that don't match your conditions on card name or custom field (AND logic). Scope the filter to only certain lists — or every list except a few — and optionally search inside hidden lists too, revealing any that contain a match. • Reports & charts Visualize your board instantly with built-in charts (no external services): - Pie chart of card count per list - Pie chart of card distribution by any custom field value - Cumulative Flow Diagram (CFD) built from automatic daily snapshots, so you can track how work flows over time Exclude lists from any report by name rule or manual selection, and scan the whole board to include every card, not just the ones on screen. • Card detail default Open cards the way you like them. Automatically collapse a card to "Comments and activity" (or expand it to full details) every time you open one — your choice, set once in Settings. Manual toggles are always respected. ★ WHY YOU'LL LIKE IT • Per-board settings — every preference is remembered independently for each board • Fast & flicker-free — hidden lists never flash on reload • Works with Trello's dynamic interface — re-applies automatically as the board updates • No account, no sign-up, no tracking ★ PRIVACY Trello Helper does not collect, transmit, or sell any data. All your settings are stored locally in your browser using Chrome storage and never leave your device. The extension only runs on trello.com board pages. ★ GETTING STARTED 1.
