Need Cmd + tab alternative

I often have 10 to 15 apps open at a given time, so hitting tab each time to get over to the right app is inefficient.

I'm wondering if there's an app that provides a grid that allows you to go up and down in addition to side to side? I'd love to be able to navigate windows too?

I looked at Witch and its not really what I'm looking for. Also tried Hotkey but the commands haven't stuck. Was thinking of trying rcmd next.

Would love any input from someone who thinks they've figured it out
