Last week, I published my first ProcessWire module - a simple Textformatter.
Github Project: https://github.com/MartinMuzatko/TextformatterAutoAnchor/
ProcessWire Module Page: http://modules.processwire.com/modules/textformatter-auto-anchor/
The module does nothing simpler than adding anchors and IDs to headings (h2 to h6) for quick navigation and for sharing sections of pages. It was a work of maybe 30 minutes, but it even got featured in the latest ProcessWire weekly.
#Why is this important?
We need more of the community to stand up and code up things that solves even tiny problems. OpenSource projects like ProcessWire depend on the community. I didn't realize what I could do with just a tiny Textformatter.
Diving into a specific topic can be easier than you may think.
