Looked up the extension and it seems only to return old windows frames, and not consistently for all users. It appears to have problems in dark mode and if unfocused. Anyhow, not sure I'd recommend it.
Agreed, some users had issues last year, all software has teething trouble, but the Mod has been updated a few times since then. I Have used Dark Mode with it for a while now, No Unfocused issues(Tested on Various Win 11 Editions, including Win 11 Enterprise 24H2.I am Going To Test It On Win 11 25H2 as soon as it becomes A Final Release In The Autumn) The consistency issues reported tend to be mostly from users who do not follow the install instructions, If It Is Not Done 100% as per the instructions it does not work Correctly.
Windhawk Mods Are A Gift To Peeps who , like us, want to Customize There PC, Not Just A Frames thing . Imagine being able to take all the things you loved about Previous Editions Of Windows, and then using them on the latest Windows Editions, Windhawk Makes That A Reality.
I Think A Windhawk Topic of its own should be created as our users could discuss the Mods they use, How They Work, and what they do. I Would do it myself but 1: I do Not Have The Time and 2: I am not what you would call an Expert user as i have only tested about 20 of the Mods specific to my needs and wants of my OS and its use.
