Extensions you like to use
One I just found recently called glean. Doesn't do anything crazy. It's just a refactoring type of extension. You just highlight the code you want to extract and it converts it all into a new component for you. You might have to tidy it up a little bit, such as formatting, but it does all the prop assignments and all that for you. Figured if anyone else has any nice ones they could also post them here.
