I've found that to really get the most value out of Jet rains IDEa you have to go out of your way to discover the built-in features and use them, things like the built-in debugger, git support, find in project, search by symbol, etc. There's a LOT in there and easy to ignore or gloss over.
A way to learn is to take the time to read the tip of the day and try out the suggestion right away. Don't disable the tip of the day. It only takes one minute a day and after about a month you'll have learned a lot.
