Discontinued! :'(

MacUpdate should have a field for discontinued apps.

I'm sorry to read at the developer's site, that he has moved on to other projects. Blackout still is (until it breaks with an OS update), one of my favorite utilities.

If I were to ditch all my system enhancement programs save one, I'd keep this on!
What a relief to my eyes. What a great concentration helper!

Update to my previous review:
there's an option to set a keyboard shortcut to enable/disable the brightness without quitting Blackout, so that's good. Pretty much addresses my issues in another way, so I'll this 4 stars.

Hey MacUpdate: allow reviewers to revise their posted reviews!

Works fine but minimum/maximum brightness settings need obvious changes:

1) MINIMUM BRIGHTNESS SETTING. Nothing worse than accidently sliding a brightness setting to the mininim setting (which is 100% black) and then releasing the slider. Do that and your only option may be to invoke "Force Quit" and then blindly quit your running apps one-by-one 'til Blackout is quit. The minimum brightness setting should be selectable in the preferences settings.

2) MAXIMUM BRIGHTNESS SETTING. Currently the maximum brightness setting is something like 85% or so. This means that you have to quit Blackout if you momentarily need to have full screen brightness. The maximum brightness setting should be "OFF", or full brightness.

Also, though not essential it would be nice to have user-defined keyboard shortcuts to increase/decrease brightness.

have been using daily (or nightly, rather) since 3.1, the new dual display support added in 3.3 is even better since i just got a second cinema display. i am now using Blackout's "Soft Edges" effect on my main display and a cursor-following spotlight on my second. can't imagine working at night without this app now. 5 stars
