Highlight the focused window with a border

[zikaari]

Description of the new feature / enhancement

I find Windows 10's built-in way of expressing which window has input focus very subtle. This StackExchange post covers this exact same concern except that one is for mac os.

I propose a feature that would draw an outline around the active window, just like how it appears for a focused text input, or a button, or a combo-box, and would serve the same purpose as well.

Scenario when this would be used?

When working with multiple windows at the same time (Slack, Terminal, Chrome), open side-by-side, or spread across multiple monitors, I often mix up which of the windows has input focus and I end up hitting Ctrl + W in the wrong window. You know the rest.,

If anyone is interested, I started implementing this feature in komorebi: LGUG2Z/komorebi#182 (comment)

Posting here for visibility and also to share the implementation approach if this feature gets put into the backlog for PowerToys. 🤞

Here is an AHK script that does the job:

This feature may reuse implementation of highlighting a window from PowerToys "Always on Top" module.
