You know what drives me crazy? Changing the render orientation. You have to set both the x and y. Want to swap the orientation? Reset the x and y. Doing that ad infinitum.

Well now you don't have to! With this add-on you just click a button and it swaps the x and y render dimensions.

You can change your orientation from where you normally change your render dimensions and if you press ctrl+shift+q it will bring up a pie menu so you can swap without going to the output tab.
