As a developer who recently switched from VSCode to RubyMine, I have found it frustrating that I could not figure out how to configure the IDE to open source files directly from the commit window. In VSCode, this was a simple setting that I could easily change, but in RubyMine, I couldn't find the option anywhere.
After searching for a few weeks, I finally stumbled upon the solution by accident. If you right-click the Commit pane tab, the option to open source directly is right there! This simple discovery has made it much easier for me to jump around my source code while editing and refactoring.
