Let me suggest HyperSwitch, you can map it to cmd+tab instead of system's switcher and it will instead just apps show you all windows for all apps as does switcher on Windows...
I'm a fan of Open Source and have a growing interest in serverless and edge computing. I'm not a big fan of spiders, but they're doing good work eating bugs. I also stream on Twitch.

It's in beta, but works on Mojave OK.
