Change in terminal when running

When I use Matlab, I often do some sort of repl by f9 on a selected chunk of code.

Sometimes these involve long running jobs - for example loading a big file.

Currently if I do this via "run selected code" in the vscode extension, obviously the engine is running in the background but the terminal interface is unchanged.

At present I have to do something like ;

LongRunCmd();
disp('done');

Or else I can't tell when the code has actually finished.

Is there a hook we could use to configure something our side? Such as to change the window colour or something (a bit like neovim plugins that allow changing cursor colour based on the mode etc).

Thanks for the extension, it's great!

Start by tracing the VS Code extension's "run selected code" flow and how it observes MATLAB engine execution; the issue names no files or tests. Define how the terminal should visibly indicate a running job and its completion, then verify the behavior with a long-running selected command.
