msstyleEditor VS keyfox

https://github.com/nptr/msstyleEditor (free), this. Also another paid alternative https://www.vistastylebuilder.com/ . BUT msstyles only apply for win32 apps (file explorer,...), not UWP and other part of system. Also editing things like that is not so easy for me, so good luck on that.

VS: Niivu’s Janguru W10 Theme modified with MsstyleEditor

to make my theme i've used WSB (mainly) and msstyleEditor ( for some specifics changes )

Started with this, followed instructions, then changed stuff i didn't like with msstyleEditor and Resource Hacker. It's a hack, so some apps don't/only partially pick up the style. Some shortcuts (custom themes live in C:\Users\YOU\AppData\Local\Microsoft\Windows\Themes) on the desktop make that less of a pain.

Msstyleeditor (For customizing the themes and creating your own, this is little hard to learn first)

So yes, you must modify it using MsstyleEditor for example so you can modify the images related to this buttons. Once you have saved the result, you can rename the original file to whatever you wish, and rename the modified backup one as the original one. Then, you reload the theme in the Personalization part of Settings, and you prey.

I've been using Keyfox for a couple days and I like it so far. There's a bunch more options at https://firefoxcss-store.github.io/

KeyFox css

Currently I'm trying this: https://github.com/alfarexguy2019/KeyFox and just realized how extremely powerful the userchrome file is, specifically how it's possible to achieve a single line control like this.

For those interested in the actual template, I'm using a slightly modifed version of KeyFox which you can find here
