Side-panel for Slack threads

Problem Context

Power users rely on Slack threads to monitor multiple conversations while working in main channels. The recent UI change forces threads to open in full-screen mode, breaking their workflow and requiring constant context-switching.

Pain Points

Users lose focus when threads block their view, forcing them to exit and re-enter channels repeatedly. They’ve tried all Slack settings but can’t restore the old side-panel behavior. This disrupts deep work and wastes time.

Impact

The disruption costs hours of lost productivity per week, reduces concentration, and forces manual tracking of conversations. Teams relying on real-time collaboration suffer from broken communication flows.

Urgency

This is a daily frustration that directly impacts work output. Users can’t ignore it because it blocks their primary way of staying updated on critical discussions while working.

Target Audience

Slack power users in collaborative roles—project managers, developers, customer support teams, and remote workers—who rely on threads for real-time communication while managing other tasks.

Solution Approach

ThreadSide is a browser extension that recreates Slack’s old thread side-panel behavior, letting users view threads alongside the main channel without full-screen interruptions. It sits as a persistent overlay, restoring the lost workflow.

Key Features

1. Multi-Thread Tracking: Lets users monitor unlimited threads simultaneously without losing context.
2. Keyboard Shortcuts: Quickly open/close threads with hotkeys (e.g., Ctrl+T).
3. Team Sync: Optional team plans to sync thread preferences across collaborators.

User Experience

Users install the extension in one click. Threads appear as a draggable panel next to the main channel. They can resize, pin, or collapse threads without leaving the main view. No more alt-tabbing or manual resizing—just seamless multitasking.

Differentiation

Unlike Slack’s native settings (which don’t solve this), ThreadSide is a lightweight overlay that works across all Slack plans. It’s faster than manual workarounds and doesn’t require admin access. Competitors either don’t exist or are clunky (e.g., third-party Slack bots).

Scalability

Starts as a solo user tool ($20/mo) but scales to teams ($50/mo for 5+ users). Enterprise plans can add SSO and admin controls. Future features: thread analytics, integrations with project tools (e.g., Jira, Trello).

Expected Impact

Users regain 5+ hours/week of productivity. Teams improve collaboration by reducing context-switching. Businesses save on lost revenue from disrupted workflows. The tool becomes mission-critical for power users.
