Yes, that is right, RubyMine does have LOTS of configuration settings. It adds flexibility—the product may fit to more people’s habits. But it adds a certain complexity too.
We do everything possible to keep IDE settings well-organized for quick location of needed preferences, but there is also a way that just works — search.
And RubyMine provides comprehensive search within IDE configuration and project settings.
All you need, is to type a word the needed preference should contain, into the search field. RubyMine will narrow the list of preference panes to ones that have this word and will highlight the found occurrences inside the UI.
Enjoy! And configure the IDE for your own preference.
