Felicity, but Pro.
Felicity Pro takes everything that was great about Felicity and pushes is further. With Felicity Pro, there is an all new redesign with deeper shadows and sharper glyphs. Many of the gradients and colors have also been improved for an all-round improved and more premium look and feel. Felicity Pro supports 400 icons at launch. This is a number that will only grow with future releases. There is also a total of 19 alternate icons at launch and you can expect this number to grow too. Every icon has been made with great care and attention to detail to ensure that all your icons have a uniform appearance. Felicity Pro has 3 different Alt Icon folders accessible through you Theming engine. These 3 folders have many different alt icon options so you can fully customize your icons. Some of these alt icons include different styled wallet icons to iOS 9/10 iTunes & AppStore Icons.
How is this better than Felicity?
Well, first (and most obvious), Felicity Pro supports almost double the icons. A total of 400 at launch (reg felicity is around 250).
All new redesign. Every single icon has been completely redone with deeper shadows and sharper glyphs. I certainly prefer this new redesign, and i am sure you will too
