Firstly, love this plugin! I've got a bit of a weird situation though... I've got a sketch to run on an Atmega2560. Everything compiles, everything works, but in the code window Serial1 is underlined red and flagged Symbol 'Serial1' could not be resolved. But when I compile I get 0 errors, 0 warnings, and like I said everything works, but the error flag in the code remains. It's not actually causing an issue, but the red marks feel like they are mocking me!
