I have been interested in GTD (getting things done) for a while and have been using the Pomodoro technique for a while now. I am always looking for a good digital solution to manage my to-do lists. I have tried, Evernote, OneNote, ToDoIst, notepad, offline paper, Google keep (which is less mainstream, but does deserves it) and Google tasks. Matt Cutts recently blogged about his version and it made me reconsider my new tab page in Firefox (my main browser). I have the Speeddial add-on to have shortcuts like ALT+1 to go to tweakers.net etc. That gave me pinned sites on the new-tab which was awesome in FF4.0 (which is natively in firefox since version 22 or something). But as Matt points out, it might distract you and a to do list will force you to focus on the things to do. I have found on a blog that this url https://mail.google.com/tasks/canvas gives you your Google tasks full screen. In Firefox you can go to the famous about:config and search for “newtab” and change the url of browser.newtab.url to the previous mentioned tasks/canvas url.
The only downside to this is, that there is no native Google Tasks app for windows phone. http://www.windowsphone.com/nl-nl/store/app/gtasks/a56d575c-7253-e011-854c-00237de2db9e
and there is no way to have the OneNote tasks on the new tab page of Firefox. Perhaps having a blank page is better and opening a to-do list/application separately on the second screen. Let me know your 2cents.
