Slack メッセージ非表示

Hide messages with a 'done' reaction in Slack channels. 🧩 I made a Chrome extension to streamline request management in Slack This Chrome extension helps you efficiently handle requests (tasks) received on Slack. 📌 The problem When managing tasks by adding requests to Slack's Later, the following problems start to arise once the count exceeds around 40: It becomes difficult to find and understand the original exchanges behind tasks, including the channel and conversation context. It becomes unclear which requests and channels completed tasks came from. 🎯 What I wanted to solve I wanted to see at a glance whether any unfinished requests remain in each channel. ✅ Extension features When you add this extension to Chrome, messages with a ":done:" reaction in Slack on the web automatically become semi-transparent. This makes unfinished requests easier to see in their normal appearance, so you can quickly identify tasks that need attention. You can also click the extension icon to switch display modes: - Normal mode (default): Messages with a `:done:` reaction are semi-transparent (30% opacity). - Focus mode: Messages with a `:done:` reaction are completely hidden. It only affects the display in your web browser and does not affect data on Slack's servers. You can use it with peace of mind.
