There's a small glitch in the Preferences window in which it doesn't snap to full size automatically. It does not show the Apply/Save/Close buttons at the bottom unless I drag the window down further.
Also, I have created custom clients with version 2.5.8, but with this beta I cannot remove the Plugins menu item from the Spark/Preferences dialog.
I have the code commented out in the MainWindow.java file, but it's still there upon execution..?? Obviuously I'm missing something there.. :-)
Thanks for a fun product.
BTW, one nice feature would be for the DND
