Too basic with few bugs

There’s no way to resize the window for the menu tab (not just the pop-out window). Also, it doesn’t allow the use of Copy & Paste shortcuts, but you can Right-Click and Copy/Paste from there. When you close the pop-out window, it doesn’t pop back into the tab, you’d have to reopen the whole app. And when you use the pop-out window toggle to return, the app crashes in a few seconds so you’d have to relunch it. Other than that, it’s good.
