I tried this little utility out and it is superb. Really phenomenal for something to use as a sketch pad to whip up some great ideas. Doing smooth chord progressions is really easy with this little plugin.

I found a lot of time to play around with ChordSpace, and I'd really like to see some small improvements, most notably being able to choose your desired scale. There are plenty of scales out there, and I'm sure there could be the option of custom scales as well. I'm sure it wouldn't be hard to implement, but programming is not an easy task as I've been a developer before.

Being able to cruise around the GUI on the screen is amazing. Those hexagrams make things so much easier because of the fact that you can change the emphasis and create diversions in the progression by simply clicking on one of the side panels.

This utility is great for beginners who don't know or understand how chords and chord progressions flow into one another. Definately worth checking out. And hopefully those improvements will be implemented in the not too distant future.
