Combine multiple split panes into single window with tabs in IntelliJ IDEA

Question

I have multiple tabs in multiple panes, but when I've move from my widescreen to my laptop, the panes no longer works well at half-width.

Can I keep all the existing files open, but move/merge/combine them into a single pane? (Without having to drag each of the tabs individually?)

Answer 1

Yes, according to Editor Basics:

To unsplit the screen, from the context menu, select Unsplit or Unsplit All to unsplit all the split frames.

Go to Window > Editor Tabs > Unsplit
