With my limited interaction with Mendix Studio Pro so far, I feel an integrated help content will be a great idea for all those using Mendix Studio Pro. Something like a tool tip in the header of each window (esp. pop-ups) where we make changes. On click of the icon it should open the page containing information specific to that particular rule/window or whatever we choose to call.
e.g. If I want to know the use of Generalization field or Persistable I simply click the help icon of this window and gives me the usage of each field/tab available on this window. I don’t need to go and search in the help contents.
