Hi there,
I don't believe there's a way to completely hide your opened scripts from view, but here are some tips to maximize your workspace:
- Select the "x" in the top right of the red box to close the search field
- Hide your toolbar by selecting View > Hide Toolbar
- Selecting Ctrl + Shift + 1 maximizes the current pane (Ctrl + Shift + 0 restores all panes)
There are also some cool ways to customize your keyboard shortcuts where you can configure a combo of the above upon startup.
Hope you find this helpful!
