Is there a way to increase the number of default brushes on the left hand brush palette? I tried dragging it down, with no luck.
Even 4 more would help!
Do you mean that you want to add more brushes to the Brush palette itself, so that they’re visible when you launch ZBrush?
You can’t modify the existing palette. But you could build your own custom palette that has the brushes you want. The instructions for how to do this are found in the interface customization section at www.pixologic.com/docs
I was looking at the docked left brush palette, not the opened full palette.
I’ll root around in the interface customization section, and see if I can sort out if I can do what I want or not.
If I knew what to search for sometimes, I probably wouldn’t come bug ya so often. 
Yep, you sure can. Turn on Preferences>Custom UI>Enable Customize. Then you can Ctrl+Drag the interface elements where you want them. Once satisfied, turn the Enable Customize button off again and save your configuration.
VERY cool, and easy to accomplish. Thanks MUCH, as always Aurick. I did hunt for that info, but danged if I could locate it.
Hmmm… on followup, it allows me to put the brush palette on the left dock (which is already there) but not to stretch it out longer vertically, so I could always see a few additional brushes.
Unless there’s a hot key combo for stretching an existing palette longer?
Scratch that… I JUST noticed that the brush palette is dynamic, and stretches to automatically accomodate the brushes used in that session… so I just selected my favorites, and then saved the config with them showing.
Something odd I notced though… zrbush does not fill my entire viewport… there is a 5 pixel space on the right of the screen, and a 5 pixel space at the bottom as well, instead of it filling my monitor. (1920x1200 res)
Any workaround to resolve that?
(that is in full screen mode…if I use window mode, I can stretch it out to fill the screen.)
Delete the ZBrush3\ZStartup\ConfigFiles\ZBrushWindowStartupSize.cfg file. ZBrush will then fill the monitor the next time you launch it, and remember that size for future sessions.
Excellent! That did the trick!
