Your Mac does not know you are trying to focus. It keeps everything open at once: old tabs, past Slack threads, and apps from another role.
Every time you switch projects/roles, you rebuild your setup.
Find tabs, open apps, drag windows back into place, and lose your train of thought.
Ikuna saves the whole setup as a named workspace: every app, tab, and window position. One click, and it is all back in under 3 seconds.
Looking beyond Ikuna for MacOS? Try Raycast for lightning-quick commands and rich extensions, Alfred for deep workflows and clipboard history, and WorkspacePro for a focused, minimal app launcher to speed up your day.
