I Built a Task Board in Vanilla JS — Here's What I Learned

I built StripBoard (https://stripboard.org) — a keyboard-first task organizer.

Technical decisions:

• Vanilla JS over frameworks (it's one HTML file)
• CSS custom properties for the theme engine
• localStorage for persistence
• HTML5 drag & drop API

What I learned:

• Undo/redo is surprisingly simple with JSON snapshots
• CSS custom properties make theming trivial
• Users love keyboard shortcuts more than you'd think

The whole thing is ~130KB and loads instantly.

What would you have done differently?
