Keyviz

So easy and straightforward to use. There's not too many styling/appearance options, keeping things nice and simple with the existing set of presets.

Gorgeous! Wish for two things: Mouse clicks + instant keys popping up (no fade in anim).

By far the most attractive and most customizable of all of the key visualization options. However, for multi-monitor setups, this unfortunately is a no go as it displays only on one monitor at a time and although there is discussion on the github for adding multi-monitor support, it has yet to happen. Would use this otherwise. Stuck with the less attractive Carnac for now.

Quite easy to use and visually appealing, with many customization options for keys and multiple filters, such as displaying only hotkeys (Ctrl, Alt, etc.), using specific colors for hotkeys or shift symbols, and showing all pressed keys at once or replacing new ones with previous ones. I would like to be able to move their on-screen placement by dragging instead of having to choose from the three alignments and margin options in the settings, but it's not a big issue.
