I'm looking forward to Task/ToDo Manager.
It should work under Android, Linux(or Web). If it's very cool, one of them is OK too, Android is preferable in this situation.
Necessary features:
Russian or English language
Possibility to mark task as finished
Interesting features: (I want as more, as possible, while it's OK, if some of them isn't avaliable)
Nice and easy-to-use interface
Possibility to choose finish time for task. After that it's showed as overdue.
Possibility to choose start time for task. Before it task is inactive and maybe shown or hide
Possibility to add nested tasks. Task marks completed when all sub-tasks are completed.
Possibility to make dependencies. If A depends on B, and B isn't finished yet, A is inactive as in third feature.
Possibility to create task in a moment without fill-all-this-forms
Syncronization between version(Android to linux or Android to web)
Notification (on Android only)
Features, that I'm not interested in:
Creating more than one todo list
sharing ToDo's
I've seen couple of managers. Best I've seen now is Task Coach for Linux, but I don't very like its interface, and there is no version for Android.
