I don't think development projects as either "APPLICATIONS" or "DEVTOOLS" makes much sense. Let's reconsider these categories

Why? Examples

• Pretty much all "applications" projects listed are dev tools (e.g. ZK Email, Anon Aadhaar, Open Passport)
• Some projects don't fit either category (e.g. zkID)

Input welcome... 😄
