Requesting to add an important feature !!

I am using Amphetamine for a while and I kinda love using it !! It’s best for iMacs , Mac Mini and the Mac Pro , but Amphetamine is’nt yet laptop ready ,, when ever I turn down the lid the my MacBook Air goes to sleep even if Amphetamine has a session opened !! May be it’s there but I could’nt find it ,, I’ll check it out and if it’s not there I plead to get this added ,, its so kind of you that you gave us such a powerfull app for free ,, thank you !!! I consider this feature to be the one and only missing feature in Amphetamine ,, It would be great to see laptop lid closing sleep problem fixed soon !!!

Awesome app

I have been using this since the day I got my macbook air. Simple yet awesome.
Recent update has brought in one issue. Notification sounds are not working post update. I tried changing sound gettings etc but still no sound. Quick search on google shows that multiple folks have hit this issue.
I have removed one star because of this issue else it deserves 5 stars

Developer Response ,

Update to version 4.1+ and you can enable sounds again.
