Hello! I'd like to begin by saying that I don't know anything about programming on a mac. I've modified some applications in terms of GUI and some minor behavior but I've done this mostly by following the steps of guides I find online. My question: Is it possible to hide the toolbar in an application permanently? I use an app that has the clear button on the upper right hand corner of the window to toggle the visibility of the app's toolbar. The thing is that once the app is closed and reopened, the toolbar becomes visible again. Does anyone know if it is possible to prevent it from reappearing every time the app is launched? Maybe through adding a plist key? It would be so awesome if you could help me! Thanks in advance!
