Great with a few suggestions

A good alternative to Caffeine that supports dark mode & retina displays nicely. It has a larger range of activation times which is great.

One critique is that the icon for on and off (a vertical and horizontal split circle) are a bit confusing and I found myself looking at the menu bar and not remembering if it was active or inactive. Would love something a bit more obvious at first glance, perhaps utilizing a solid fill for on and empty fill for off?

It would also be nice if it truly lived in the menu bar. The activation options could be put into a dropdown menu from the icon itself rather than a new window popping up in the center of the screen and taking window focus from the foreground application. What I like about caffeine is the quick activation/deactivation that doesn’t steal focus from windows.

Otherwise, it’s a good keep-awake utility that is up to date for Yosemite & retina displays.
