I'm with Shiu. ;-)
I'd suggest a separate section for 'bug reports' as well.
There might be a later version, however on the Mac version I've found CTRL+Z to be sporadic (but saw this was previously mentioned) and also if you try to rename something in the rename dialog box then the 'backspace' key deletes characters to the right rather than the left. (I can give more precise details if this isn't clear).
Great product though! :-)
