Correct, works great. Just remember to disconnect the port on the terminal program before reusing or launching the Arduino IDE and reconnecting to the port after you have uploaded a sketch from the IDE. There is a connect/disconnect button of the Brey terminal program's GUI. No need to close the Arduino IDE, you can leave it opened as well as the terminal program. The key is that the Arduino IDE is well behaved about disconnecting from the USB comm channel automatically once it is done with the upload command.
The bray terminal GUI even has a handy DTR button so you can reset the attached Arduino board just by clicking it any time you want to force a reset to the attached Arduino board.
