Distraction-free mode could include hiding the bottom panel.

Describe the project you are working on

It's not for a project.

Describe the problem or limitation you are having in your project

When I switch between the 2D editor and the script editor I want to hide the bottom panel when I have the script editor active, but then when I switch to the 2D editor I want the panel to return to its state, this is a pain to do manually.

Distraction-free mode will also include automatic hiding of the bottom panel when the script editor is visible.
Failing that, you could add an option to godot to do this automatically.
The bottom panel will be hidden when the script editor is activated and will return to its previous state when the 2D editor is activated.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

When you switch to the script editor, distraction-free mode will hide the bottom panel.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

No

If this enhancement will not be used often, can it be worked around with a few lines of script?

idk

Is there a reason why this should be core and not an add-on in the asset library?

This was an intentional change made back in 3.2.3, so that it's possible to do some work while in the distraction-free mode.

If you want more control over what to hide while in distraction-free mode, I feel we should provide individual shortcuts/buttons to hide the left/right dock and bottom panel: #1441

I mainly use the distraction free mode to see more of my code. Out of everything that could be hidden, the bottom panel is the worst offender when it comes to hiding code as it takes from the script view's height.
More annoyingly, it reopens everytime I run the game :(
I feel like there's some room for improvement here.

@Robert-K There is an editor setting that can prevent the bottom panel from opening when running the game, run/bottom_panel/action_on_play.
