If you would like to precisely position your application windows without using any third-party tool, you can build a versatile script in Automator to snap windows to portions of your screen. You can give yourself multiple options such as the Left Third, Right Two-Thirds, corners or anything you can come up with. Then you can put the workflow into the Services menu where you can quickly trigger it with a keyboard shortcut. The framework in this JavaScript/JXA script can be used to develop your own customizable window organizing tool.
Check out Building an Automator Script To Snap Windows Into Position at YouTube for closed captioning and more options.
Here is the final script:
function run(input, parameters) { app = Application.currentApplication(); app.includeStandardAdditions = true; var frontAppName = Application("System Events").processes.whose({frontmost: {'=': true }})[0].name(); var frontApp = Application(frontAppName); var areaChoices = ["Left Third", "Right Two-Thirds", "Top Left Corner"]; var area = app.chooseFromList(areaChoices, {withPrompt: "Where?"}); var displayText = app.doShellScript("/usr/sbin/system_profiler SPDisplaysDataType"); var displayInfo = displayText.split("UI Looks like: "); for (var info of displayInfo) { if (info.indexOf("Main Display: Yes") > -1) { var infoPieces = info.split(" "); displayWidth = infoPieces[0]; displayHeight = infoPieces[2]; break; } } if (area == "Left Third") { frontApp.windows[0].bounds = {x: 0, y:0, width: displayWidth*.3333, height: displayHeight}; } else if (area == "Right Two-Thirds") { frontApp.windows[0].bounds = {x: displayWidth*.3333, y:0, width: displayWidth*.6667, height: displayHeight}; } }
It has been extremely useful, and the explanation very clear. many thanks 💚
