I’ve also used Fluid to make an app for Mac.
However, if you use Windows, there’s an equally good alternative : Chrome’s Add to Taskbar, available from Settings > More tools. Check the “open in window” box and what you’ll get is
- a desktop/taskbar shortcut with Asana’s logo
- that launches Chrome in “chromeless” (no tabs, bookmarksbar, etc) mode so it looks like a native app
This way, you can keep it open all day and have it be separate from your Chrome tabs.
