My job involves programming, and I often use VSCode for writing code and XCode for running it. Switching between applications interrupts my workflow, so I developed Window Fusion, which binds VSCode and XCode together and minimizes XCode to make it appear like a small widget within VSCode. This greatly enhances my efficiency in managing windows. You can try combining different applications, such as Finder + Finder, Office + ChatGPT, or ChatGPT + ClaudeAI. Additionally, you can save window layouts to a separate application, meaning you can create an app whose functionality equals two Finder windows. This app also offers numerous shortcuts to assist in window moving and resizing.
wow, very interesting! > VSCode and XCode together and minimizes XCode to make it appear like a small widget within VSCode. This greatly enhances my efficiency in managing windows. This use case makes a lot of sense. I'm excited to try it for browser + VSCode when testing changes.
Thank you for your support. If you encounter any issues during use, please let me know at
The app no longer opens for me, it opened on the first run and after I paid for the license it no longer opens; Macbook Air 13" M1.
I'm sorry, this bug has been fixed now. Please re-download the app Best regards
This is very useful, makes me wonder why I never thought about it before?! I know Arc for Mac does this, but doing it for any app would be so so productive! All the best for the launch :)
Thank you for your recognition!
It won't open for me, which started right after I paid.
same issue for me.

Useful! But does this really need to be a subscription service? 😅
