Some applications simply move well together. For me, usually whatever app I am using to read, and whatever app I am using to take note. If you are the kind of person who always has many windows open, however, it can be difficult to keep this type of program sets together.
Here here glueA free and open source app from Ukraine-based developer Andry ConsentenovReally shines: This application lets you connect any two desktop windows so that they should be shoulder to shoulder, even when you move them around. If you change the shape of one vertically, the other will grow or shrink to match it.
The result is that two windows originally act as one. How useful it is depends entirely on your workflow, but I can imagine all types of easy pairing. You can glue your glue to the list app on your email app, so that you can put your daily tasks on top of the mind. You are working on your browser, or that document you are working. Or you can pin a terminal on your finder window. The issue is, you can add any two applications in a way that visually suggests they are part of the same workflow.
How to use glue on Mac
The gluing process begins by clicking on the menu bar icon and clicking “Add glue” or using the keyboard shortcut (F9 default). After doing this, you can connect any two windows into each other – you will see a blue glow because one window contacts the other, allowing you to make sure that the connection is correctly. You can either open the windows from the menu bar, or simply shake one of two windows with cursor.
What do you think so far?

Settings allow you to decide whether the application will be open when your MAC is, whether it allows the shaking to feature, determine the pixel gap before the gluing starts, and set the keyboard shortcuts for both gluing and unging.
Gum is probably not necessary for everyone, but it is a killer app for those whose minds work in a very special way. If you are one of them, you will be surprised how you lived before glueing two desktop windows together.
