I tried CodeWeaver's site but it's a dogs breakfast. Want a simple list of windows apps that'll run via CrossOver? Lotsa luck- i gave up. And forget a graduated rating system (A: runs perfectly, B: mostly runs..etc.).
I'm eager to cut my dependence on Windoze but, despite Linux pride in customizability, it's short on appearance tweaking apps (Clutter Clock, CinemaDrape, WindowsFX, CursorFX etc. etc.), so i'd be very dependent on CrossOver.
Can anybody tell me how well it works? I hear it's just a front-end to Wine, so shouldn't run much better than it (and it runs poorly). Is this correct?

Must also say- Deepin's site is a mess, with english being a distant afterthought (registration form for "International forum" (this is no english-only forum!) is in chinese!! That's depressing because if Deepin is easier, it's still Linux.

Have you tried any other distros? You may have more luck with others, certainly when it comes to websites and documentation.

Regarding Crossover - I never really used it because I found more success just getting on with Wine and Winetricks (lets you fine tune the config) - you can in fact set each Windows program to use a specific version of Windows and essentially ideal config for that app. I would read up on Wine and winetricks as a starter - it may actually be easier than a wrapper program where you can't really see what is going wrong. A lot of successful Wine test results are done on Ubuntu, probably because it is popular (as are many other Debian based distros), be Debian based distros do tend to have good compatibility.

Another backup options is to have a Windows VM. It is possible to set up apps to run via VirtualBox as if they are native to your Linux desktop - they are running in a VM technically, but visually they are just another app running (e.g. no VM window with Windows taskbar, just the app window).

CrossOver is basically a tweaked version of wine that includes configuration tools and installation scripts. (my limited knowledge ...)

No Windows tweaking application will have any affect on a linux desktop, well at least as far as I know. The desktops are very different from each other.

My opinion is that you should use a different distro to start.

Crossover tends to be more advanced than wine. Buying crossover products help support wine development (pretty sure they still do).

On the tweaking side - yes, not sure what Windows tweaking tools would do. Linux is infinitely more customizable than Windows, so you just need to know the tools. You should play with some Desktop Environments which are the GUI that sits on top of your distro. I always push this, but Debian 10 gives you the ability to install a whole bunch of DEs on installation and you can logout and switch between them - I did this to test them out and settled on Cinnamon as it is very customizable, quick and feature rich (and appears not to have any glitches at all).

It you want to do lots of desktop tweaking, then give the KDE Plasma desktop a try. Lots of bling built in and easy to configure and install new stuff.
You can install KDE on any distro, but if you start from scratch, then try the Neon distro which is from the KDE team and pulls their latest code.
