Good feature and thanks for letting us know Plamen.But once we made changes is there a way to push these changes automatically to static app files?
It's a gold mine. No more switching to the Shared components for editing. Plus you get all the cool features of VS Code editor.
If you have used APEX Nitro, it's very close as functionality. It's only built-in now 🔥
Plus there is more to Session Overrides, allows changing the timezone and language during the session, so you can do some valuable tests and so on. You will like it 👍🏼

Session Overrides are a convenient way for developers to quickly change values in the session that the APEX engine is typically responsible for, like File Paths, Additional Files and Globalization Attributes.
Here is the official documentation.
Okay, but how do Session Overrides speed up the development process?
They speed it up because it allows using a local JS or CSS files on your machine which are referenced in the app. This way you don't have to go to the Shared Components and edit your Workspace or Application files before you can see the results in the app. Very convenient feature - once you start to use it, you'll never look back. Small detail - it's available since APEX version 22.1
