Make windows Acrylic / Transparent

[jt-github]

Summary of the new feature/enhancement

It would be so awesome (if not necessarily easy to code) to be able to select areas of ANY application that you wanted to make acrylic.

Example: "Acrylicize" Outlook so that everything but the list of messages and the message frame was transparent with a blurred background to help focus the user on what matters (just the next evolution from using the dark theme with it).

Proposed technical implementation details

Such a PowerToy would allow:

1. Selecting an app
2. Selecting one or more areas to modify
3. Seting transparency, blur, tint, and/or other visual effects to be applied to the objects seen through those elements, possibly with some presets like "Windows Acrylic", of course
4. Selecting what the transparent areas reveal:
   1. The applications beneath it (the way Windows does such things currently)
   2. The desktop background (act as if applications beneath it do not exist)
   3. The applications beneath it when not maximized and the desktop background when maximized (I suggest this be the default because it's awesome)
5. Enabling/disabling per app (and remember settings while disabled)
6. Resetting settings per app (to go back to defaults in case things get weird)
7. Changes to be saved across application close/open and system restarts, of course.
8. Starting automatically with Windows as a service, etc.

A user should never have to draw areas that should be affected but rather select existing window elements both on classic/legacy applications and UWP apps, just as developers are currently used to doing when using "developer mode" on all modern browsers.

This will obviously cause some serious redraw and possibly some performance issues, so there should probably be warnings to that effect.

I wrote the original idea on:
https://docs.microsoft.com/en-us/windows/uwp/design/style/acrylic
(which shows off acrylic's awesomeness, too)

this would have a big impact on battery life and based on how you're talking about this, we'd have to DOM inspect / inject into the app. That could be ... hard

[jt-github]

It would definitely require more horsepower and yeah, I assumed coding it would be a challenging effort just because of the inspection/injection required, but if any team could pull it off, it's the @powertoys team! :)

There is an old app named Glass8K or something which has ability to turn any app to partly transparent. It can change a window opacity. But it is abandoned sadly. It would be great if simething like that could be implemented.

[jt-github]

Yes, that's Glass2K (as in The Year 2000, probably) by Chime Software and, amazingly, it still works on the latest version of Windows 10, but controlling opacity is only half the game. It's the acrylic affect specifically (that adds in blurring, etc. on top of transparency) that I would love to apply to all windows except the active one.

Whoops! 😅

So did we say screw it?

I vote for no involvement of spirally grooved solid metal cylinders, but I can totally understand if this is shoved into a backlog since the OS itself doesn't support this (at least natively).
