Most used app on my computer

It does work great right out of the box, but if you invest a few minutes to learn about everything it can do you won’t be sorry. Custom snap areas for certain programs and/or workflows, keyboard shortcuts to quickly move the window to the next monitor (& back), etc.

** Some Comments on Other Comments **
1 - Multi-monitor support is great, even when all monitors are different resolutions (e.g. 5K & 1080 etc.).
2 - JoshuaD80 claims that he cant make Chrome take up 2/3rds of his monitor with Slack on the other 1/3rd. He hasn’t watched the tutorial video because it is very easy to set this up with hotkeys and/or custom snap zones. The software doesn’t come (uselessly) pre-programmed with all the thousands of possible screen combinations that anyone could want. Just make your window the size, shape, and location you want, then create a new hotkey and custom zone to drag it to that will return it to that place. You can even limit it to only working for a particular program (e.g. Chrome, but not Safari).
