I asked about this on twitter recently but no responses. Can anyone list their absolute favourite open source client side web based todo lists? It seems like there would be a lot as its everyones favourite personal project (I do have my own). however most seem to be extremely basic. I am mostly judging by UX features and polish, something that works really well webbased + tablet + mobile would be a plus. If anyone is interested in why, I am an author of pouchdb, a javascript library that aims to make syncing offline apps incredibly easy, I plan to take a standalone todo app and modify it to sync the data to see how easy it is / make a tutorial.
