This app fits the bill perfectly! The only quirk is that it doesn't seem to recognize a right-click on the menu have to control-click. Maybe that's for nostalgic reasons...LOL. An extremely useful little app.

gtcaz: you did see the "Activate for..." submenu when you "command click" on the coffee cup, right? So currently it defaults to "forever" but you can override that for a given session with the "Activate for..." menu. Were you asking for a way to change the DEFAULT timeout from forever to something else?

Great little app! The only thing I'd like is on options to set a default timeout period (so I don't come back in the morning with my iMac still wired and wide awake on caffeine).

I am an optometrist and use an iMac in the exam room to control a second monitor. If I leave Caffeine running, I prevent the second monitor from sleeping too! fantastic! and Thank You...

Nice little app. I'm all for anything that let's me be even lazier than I already am. Well done!

my only wish is that it could also stop sleep when you close the laptop, like how InsomniaX does.

A non intrusive great little does-as-you-wish app for when you want to keep your computer from sleeping that works well. What more can I say?

Caffeine is great. I can't imagine something so simple and so useful. Free and tiny to boot. I do miss the ZZZ. Oh well.

I don't want to be a nitpick (especially since I love this program), but from a usability perspective, the new menubar icon isn't clear enough to display the actions of the toggle. It may be prettier to look at, but it's not the best choice from a gui usability point of view, as there is not enough of a direct visual connection between a cup of coffee and the screen going to sleep.

Genius, beautifully done.
