Toggle "Output window Follow selected track" On or Off

Hi, @Nicolas_Bourgeois,

I have been meaning to implement this for a while. This will start and stop the script by running the script more than once:

let lastFocusedTrackName;

function main() {
    try {
        let newName = sf.ui.proTools.selectedTrack.normalizedTrackName;
        if (newName === lastFocusedTrackName || newName === undefined) return;

        lastFocusedTrackName = newName;

        // If An Output Window Exists and An Output Window is open
        if (sf.ui.proTools.mainTrackOutputWindow.exists && sf.ui.proTools.selectedTrack.outputWindowButton.value.invalidate().value !== 'open')
            sf.ui.proTools.selectedTrack.trackOutputToggleShow({ onError: 'Continue' });

    } catch (err) {
    }
}

function runForever(name, action, interval) {
    // If globalState is defined, then stop the loop 
    if (globalState[name]) {
        log(name + " is Stopping");
        globalState[name] = null;
        return;
    }

    // Start the loop
    log(name + " is Starting");
    globalState[name] = true;

    sf.engine.runInBackground(function () {
        try {
            // Keep looping while this named loop is still active
            while (globalState[name] && sf.ui.proTools.isRunning) {
                sf.engine.checkForCancellation();

                action();

                sf.wait({ intervalMs: interval, executionMode: 'Background' });
            }
        }
        finally {
            globalState[name] = null;
        }
    });
}

runForever("Output Window: Follow Selected Track", main, 500);

Thanks guys :) that's exactly what I need

just a question @Owen_Granich_Young
I've tried the script in the post you mentioned.
I've put this script on a streamdeck key as a toggle.
Does the script still run in background while "disabled" or is it "kill" and relaunch when relaunched ?
Meaning does it takes ressources while disabled ?

Thanks
