Hi,

There is some new functionality which you can switch off but I think that once you understand it you will find it to work the way you want.

Here are a few bits of info

1) If you want to view arduino library or core sources. Then click on the project in the solution explorer and use the "Show arduino core and library sources" command to toggle the sources in/out of the project. Visual Micro will create the shortcuts to all source code in a place within the project that will be ignored by the compiler.

2) If you want to include add-hoc code for reference purposes then right click the Solution in the solution explorer and click "Add Solution Folder". You can create as many folders in the SOLUTION and not the PROJECT as you want. Then add and organize your reference code into the solution folders. 

Your project should end up quite clean whilst also giving the ability to organize the project code into sub folders and to include/exclude code into the project to control what gets compiled and what is backup/test code.

The new system has also allowed Arduino libraries to be edited, developed and debugged locally within the project.

I hope this makes sense. Please say if there is a feature you feel you have lost and can't see the point of this additional flexibility and I will point you to the "Compatibility" (arduino) section of "Tools>Options>Visual Micro" where you can switch back to the simpler system.
