If you find the icons in the top bar horrible, just like me, its easy to change. U just have to close the app, than open the get info menu for the app, than remove the .app extension. The app will become a folder. Than open it and search for the files loaded and unloaded .png. Now replace them for new icons that u have choosen. I reccomend the icons from the similar program Caffeine. For having them u have to download it and do the same til you find its icons inside the app folder. They are pretty cool. Just remember to change the name of the new icons to loaded and unloaded, otherwise the app (insomnia) wont find the files. Than put back the .app extension in the folder name. It should become an app again, and once you launch it, the new icons should appear the bar. It worked pretty good to me! Good Luck!!
