Rated 4 out of 5 stars
Good idea and very well executed. The list of suggested events is good, but allowing for custom events (granted, if you know what you're doing) is even better. A couple of issues I found:
1) Having more bundled sounds may be a good idea, because not everyone will go through the trouble of locating local sound files for events.
2) Did not work in Mac. Enabled events did not show the "check" next to them in the list, and the events did not trigger the sound.
Import/Export is great too. Good work.
With Jose's big help, the problem on Mac has been solved (in fact it's my mistake) in mid September. And now I'm waiting for translations and plan to nominate this addon to public when next version is ready.
