* Scaling GUI elements option (scaling GUI elements from 50% to 200% of its original size in 25% increments) - great for people using very big screens on one hand, and for those using netbooks on the other (if there are such out there)
* Text labels on all frames (and tabs too) should definitely be BOLD. They're too thin and insignificant looking currently.
* Tabs could look even better and more like a part of the interface. Example:
(By the way, LFO defaulting to 200 Hz when it's turned on the first time is not a good sensible value, IMHO.)
* See image above. The right side of the frame could have a bit more padding between the inner frame and the edge of outer frame. It would look nicer.
* When you collapse a frame, the collapsed frame should also be round. Much better!
* In case you add more padding around the inner frame (which I think should be done), then the collapse buttons should be placed a little bit lower to follow the padding, of course.
* The vertical text on the frames should be center aligned with the collapse button. And perhaps the collapse button could be a bit cleaner looking without so much antialiasing (bottom right edge of the button looks as if it's not there, too much 3D effect on it).
* Why does the pan indicator have this white line, and volume indicator does not? I think it looks better without that white line:
* The buttons in the top left need to stand out more, currently they look like they are embedded too much into the background.
Sorry if I'm "pixel-hunting" too much! I'm sure more will be incoming
