I was needing an alt-tab replacement that allowed me to search open windows (yes I have that many windows open!), and after a few minutes of searching I found the amazing utility Switcher. The animations are a bit slow, but you can turn them off and have a really rapid alt-tab replacement utility that allows for search! Search is amazing, I have 20 windows open right now, alt-tabbing through them is generally a pain, but I type at 120WPM, so searching is faster than using my mouse of having to hit “alt-tab”, do a visual check of which app is selected, rinse, wash, repeat.
My only complaint is that when using multiple monitors, which monitor search results show up on seems fairly arbitrary. It also seems to split across screens, but it would be nice if there was a way to tell it to stick to one screen or the other.
But those are minor complaints compared to the amount of time and frustration I am saving with it!
