This Free Mac App Glues Two Desktop Windows Together
Some apps just work well together. For me, it’s usually the app I use for reading and the app I use for taking notes. However, if you’re someone who keeps multiple windows open at all times, it can be difficult to keep those sets of apps together.
This is where Glue , a free, open-source app from Ukrainian developer Andrey Konstantinov , really shines: It lets you glue any two desktop windows together so that they stay side by side even when you move them. If you resize one vertically, the other will grow or shrink to match.
The result is that the two windows work almost as one. How useful this is depends entirely on your workflow, but I can imagine all sorts of handy combinations. You could combine your to-do list app with your email app so you can keep track of your daily tasks. You could insert your AI app of choice into your browser or the document you’re working on. Or pin Terminal to a Finder window. The point is that you can connect any two apps in a way that visually makes them seem like they’re part of the same workflow.
How to Use Glue on Mac
The gluing process starts by clicking the icon in the menu bar and pressing the “Add Glue” button or using the keyboard shortcut (F9 by default). You can then merge any two windows by dragging one to the other. As you move one window toward the other, you’ll see a blue glow to confirm that the connection is correct. You can separate the windows either through the menu bar or by simply shaking one of them with your cursor.
The settings let you decide whether to open both apps at the same time on your Mac, allow the shake-to-unstick feature, define the gap between pixels before sticking begins, and set keyboard shortcuts for sticking and unsticking.
Glue may not be for everyone, but it’s a blast for those with special brains. If you’re one of them, you’ll wonder how you ever lived before you learned how to glue two windows together on your desktop.
