better productivity guide

Hello,

the productivity guide is great! I have some ideas to improve it, though:

• Add many more things to it :-)
• "Go crazy" somehow when the user doesn't use a feature which is considered particularly awesome (User / Jetbrains rating of features? Other user's statistics? I don't care, you implement it.). Or particularly basic, like Ctrl+N and code completion.
  
• In productivity hints of wait dialogs do not show features which are often used by the user. Focus on rarely used ones, especially the "awesome" ones (see above)
