Great little Utility. I like the ability for setting which programs will keep the system awake, it's very easy to use, has a great little Icon in the top Menu bar and of course is free...!
Just one thing and if the Dev could possibly take note; the reason I downloaded this was in the hope that I could prevent the system from going to Sleep upon closing the Lid/Screen on my MacBook Pro (thus keep the system awake with MacBook Pro in 'clamshell-mode). Sadly this is not the case and my MacBook Pro 8,3 goes to sleep whenever I close the screen. Therefore if this ability could be somehow implemented into Wimoweh with maybe some additional options such as never sleep when lid is closed (plugged into power supply), sleep after certain conditions are met with lid closed (i.e. set time or finish of tasks etc) and shutdown while in/from sleep if on battery with 5% power remaining - then this would be fantastic and a real Gem.
For those that would not like this proposed feature, then they simply don't have to enable it, then no one is left out and everyone's happy.
With regard to my model of MacBook Pro 8,3 (17" intel i7, early 2011) Apple state that clamshell mode 'is' supported for this mode, however the only way I have ever been able to use it in clamshell mode is when an external display like the Apple 27" Thunderbolt Display was plugged into it; closing the MacBook Pro would retain display on the Thunderbolt while switching the MacBook Pro's LCD screen off and preventing the MacBook Pro from sleeping. The Macbook Pro NEVER overheated and always felt the same if not cooler because the LED backlighting was off in the Lid and so was the LCD screen (which gets lit by the LED backlighting.
Its still a great App and well worth having as a very handy and useful Utility.
(I didn't rate full 5 stars for stability having only just installed it as of same day of this post/review, therefore have not tested it for long enough.)
