The nice thing about DisplayFusion is how customizable it is, and I find that everyone uses it quite differently. I'll tell you how I personally use it, and how it benefits me:
- Creating custom window sizes is crucial for browser testing at different screen resolutions (800x600, 1024x768... etc)
- I use the "Toggle window always on top" all the time for keeping an important document (like my notes) over another window while it loses focus
- Multi-monitor taskbars help keep my windows organized per-monitor
- Version 3.3 has taskbar shortcuts which you can use to launch that application on that monitor, which is fantastic when you have 3 or more monitors
- I use window snapping to line up my windows easily and quickly
These are just a few of the main ways I use DisplayFusion, I'm sure you'll have different needs, but this is a good start.
