MacOS – Cmd + Tab showing different windows from a single app

If you hold command and quickly tap tab you will cycle between your two most recently used applications without bringing up the heads up display.

If you want to use a third party app Witch has options to ignore minimized windows.

You can use an app called witch.

It allows cmd+` switching using MRU order and a popup overlay similar to the default cmd+tab overlay. You can also, optionally, show window previews and many other customizations.
