Sorry should have said I already use ESlyrics 0.5.4.1028.  And I guess you don't want me to downgrade.

With this version, when you go to panel preference advanced, enable custom layout doesn't work.

let activeRequests = [];
let isSafeToExit = false;

function checkAndExit() {
	if (isSafeToExit && activeRequests.length === 0) {
		fb.Exit();
	} else {
		setTimeout(checkAndExit, 100);
	}
}

function bioOnStateChange(resolve, reject, func = null) { // credit regorxxx
	if (this !== null) { // this is xmlhttp bound
		if (this.Status === 200) {
			return func ? func(this.ResponseText, this) : resolve(this.ResponseText);
		} else if (!func) { return reject(this.ResponseText); }
	} else if (!func) { return reject({ status: 408, responseText: this.ResponseText }) } // 408 Request Timeout
	return null;
}

// May be used to async run a func for the response or as promise
function bioSend({ method = 'GET', URL, body = void (0), func = null, requestHeader = [], bypassCache = false, timeout = 5000 }) { // credit regorxxx
	return new Promise((resolve, reject) => {
		fb.RunMainMenuCommand('View/Console');
		const xmlhttp = new ActiveXObject('WinHttp.WinHttpRequest.5.1');
		// https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest#bypassing_the_cache
		// Add ('&' + new Date().getTime()) to URLS to avoid caching
		activeRequests.push(xmlhttp); // Add to active requests list

		xmlhttp.Open(method, URL + (bypassCache ? (/\\?/.test(URL) ? '&' : '?') + new Date().getTime() : ''), true);
		requestHeader.forEach((pair) => {

		}

		xmlhttp.SetTimeouts(timeout, timeout, timeout, timeout);
		xmlhttp.Send(method === 'POST' ? body : void (0));

		const timer = setTimeout(() => {

			} finally {
				clearInterval(checkResponse);
				activeRequests = activeRequests.filter(req => req !== xmlhttp); // Remove from active requests
			}
		}, timeout);

		const checkResponse = setInterval(() => {
			try {
				if (xmlhttp.Status && xmlhttp.ResponseText) {
					clearTimeout(timer);
					clearInterval(checkResponse);
					bioOnStateChange.call(xmlhttp, resolve, reject, func);
					activeRequests = activeRequests.filter(req => req !== xmlhttp); // Remove from active requests
				}
			} catch (e) {}
		}, 30);
		setTimeout(() => { // Simulate foobar exit during request
			// Do cleanup
			clearTimeout(timer);
			clearInterval(checkResponse);

			console.log('Aborting all active requests...');
			activeRequests.forEach((request, index) => {
				try {
					console.log(`Aborting request ${index}`);
					request.Abort();
					console.log(`Request ${index} aborted successfully.`);
				} catch (e) {

				}
			});
			activeRequests = [];
			console.log('All requests have been aborted.');

			checkAndExit();
		}, 500);
	});
