I use Rectangle [1] for window resizing, I have an ultra wide and it allows me to resize/move windows in thirds with a simple keystroke command, which I really like.<p>I also use it frequently to maximize the window to screen view without having it go full screen.<p>[1] - <a href="https://github.com/rxhanson/Rectangle">https://github.com/rxhanson/Rectangle</a>
Personally, I find myself using Raycast (a spotlight alternative, like Alfred) and DropOver (a convenience tool to improve drag-and-drop functionality) very often
