Need testers for a new IDE

Thought I would try this as I need some functionality which I cannot get with standard IDE. (Win 7/64 bit & Arduino UNO)
Getting quite a few compile warnings regarding HardwareSerial. Does not stop the sketch running though!

I really need to be able to "cut" from the Serial terminal output, for debugging/documentation purpose.
Unfortunatily, ArduinoX does not do that at this time! Will it be able to in the future?
I will keep an eye on this development, as the standard IDE is not all that good!
