I use it both on my laptop and my desktop and the list is synced by Dropbox. The best thing that I can say is that it just works and fits very well into my workflow but instead of a simple text-file I now have a nicely formatted list.
For people that want this outside of Sublime you can get TaskPaper, same thing (I guess this plugin was based on taskpaper). Available at the apstore. I use it daily as my todo manager.
If you like TaskPaper—which by the way it's awesome—you should check [FoldingText], by the same developer. It's currently in alpha, and expand on the idea of TaskPaper adding some interesting features, like the builtin timer.
I just did and I like quite a bit. It is very interesting. How much interesting it will stay really depends on the price. I don't intend to ever spend $25 for TaskPaper, so unless it is a $4.99 purchase, I will pass.
When I read "opinionated" these days, I automatically translate it in my head to something like "This software only does part of the job, but that's by design".
Google Tasks (The task mini-app in Gmail and Calendar) seems like it's been neglected for a while now. Before asking for workable Android and web clients, I would want tagging in addition to or instead of nested lists, and a little more effort integrating it with both Gmail and Calendar. Search integration a must, too.
It's a shame, because except for those caveats I would have been on board with it a long time now, and I still haven't found anything that truly works for me, either. I've mainly been using Gmail for my inbox and a single taskpaper file in Simplenote or Dropbox, but I migrate and try something new every odd month.
The other Google teaser that's a great concept but needs fleshing out in vital areas: The Scratchpad Chrome extension. Why does it seem like Google is bored with the simple stuff?
Edit: Wunderlist doesn't have tagging either. Another one that got away.
The GTasks app available in Play Store is the most expensive and most useful app I've ever bought. It receives consistent updates and has been around since before the Google Tasks API existed. It's very easy to make a task into an appointment. It also has search. Tasks are already available from GMail and Calendar web interfaces.
I don't see the need for nested lists or tagging, I think that overcomplicates a personal task list.
By the way, same thing for vim: https://github.com/davidoc/taskpaper.vim
