I'm the developer of Pressability, a simple, grayscale icon pack for your home screen. I'm constantly updating it with new icons and am currently working on implementing fragments to improve the the app on tablets. I purposely left out the icon request feature as an incentive to download Pressable, the colored paid version. Don't worry though, as this free version will receive all the same icons only at a slightly slower pace. If you have any suggestions, please comment below!
