It would be really nice if we could drag the tabs off the main window or have it be a ctrl + click dropdown option to make the tab a separate window.
the reason I would like to see this feature and like the idea so much is that when I am using Mcreator I am on a computer with multiple screens. And it would be nice if I could use all those screens instead of having to do everything on one screen.
I know this may entail a fair bit of coding but many other IDE like applications have the option for separate windows. And on top of this, it would add to how full and well built the overall application is.
