It is implemented in the Web App, but not in the desktop app.
Why?

Yes, I second this. This idea would be REALLY useful!

It’s a nice idea.
Since I am only a beginner user of cTrader I’m not sure whether this is possible by creating Workspaces. But as far as I now Workspaces do not exist in the desktop application.
But even it would be possible, this is a nice idea.
However, there’s a chance that I could find another idea which would be much more useful.
