Since its launch in 2013, Slack has metamorphosed from a standard messaging app into one of the most thorough collaboration and productivity platforms available today. Initially designed to assist with email dependency, Slack has expanded into a central hub for workplace productivity, integrating with thousands of third-party apps, automating workflows, and encouraging seamless communication across distributed teams.
Slack has expanded its functionality significantly in recent years, with AI-powered search, automation tools, and enterprise-grade security becoming standard.
The platform’s adaptability makes it invaluable for IT leaders aspiring to streamline comms while preserving governance and compliance. Despite these myriad advancements, many game-changing features remain underutilised. Understanding and implementing these can not only drive significant efficiency gains but also fully maximise the value of your Slack investment.

10 Underrated Slack Features for Collaboration and Productivity in 2025
1. Slack Canvas: A Dynamic Workspace for Persistent Collaboration
Slack Canvas is a transformative knowledge-sharing asset, yet many IT teams overlook its potential. This feature means users can generate persistent, collaborative documents directly within Slack, allowing teams to draft project plans, share meeting notes, and compile resources without app-switching. IT leaders can leverage Canvas for tasks such as onboarding documentation, internal wikis, or even structured brainstorming sessions.
2. Huddles with Video and Screen Sharing
While most IT leaders leveraging Slack might recognise Huddles as a valuable tool for voice chats, their video and screen-sharing capabilities remain underused. Instead of defaulting to traditional video calls, teams turn to Huddles for fast, casual video discussions that might feel less intrusive or high-pressure than scheduled meetings. This feature can cultivate a more easygoing and productive collaboration culture, reducing unnecessary calendar clutter.
3. Workflow Builder for No-Code Automation
Workflow Builder enables teams to automate repetitive tasks without demanding technical expertise. Among its plethora of benefits is the capacity to automatically route IT requests, institute daily stand-up reminders, or streamline approval processes; this feature intends to help admins and users save time and minimise manual effort. IT leaders can encourage adoption to enhance operational efficiency and reduce bottlenecks.
4. Slack Lists: Task Management Without the Hassle
Newly added last year, Slack Lists introduces a lightweight but robust task management system directly within the Slack platform. Instead of relying on third-party tools, teams can produce, assign, and track tasks in one easily navigable place. This feature is handy for tracking action items from discussions, meaning IT leaders can monitor accountability without impacting workflow.
5. Custom Sections for a More Organised Sidebar
Many users struggle with Slack’s sidebar clutter, yet custom sections remain an overlooked solution. Organising channels, DMs, and apps into categorised sections—such as “Priority Projects” or “Key Stakeholders”—can refine navigation and positively influence context-switching fatigue.
