I've released a Photoshop plugin focused on automating and optimizing the delivery of UI designs for development. It automates the slicing and
exporting of PNG assets, and allows you to create matching UI design specs
with concise information on element positions, dimensions, margins, font
It's a handy tool to greatly speed up your workflow while ensuring the consistency of your design deliverables. It's made for both individuals and design teams working on for applications, web sites, mobile apps, and similar.
Im an advocate for writing functional specs. Here are 3 reasons why I
believe specs facilitate development of Websites and applications:
1) Specs serve as the blueprint for the developer, which enables them
to review the project and start coding without delay. Would you build
a house without a written plan?
2) Specs that are reviewed/approved by project stakeholders help
ensure that the finished product meets expectations.
