Why did you choose a "check" icon for entering new todos?
I find the check icon counter-intuitive, as it seems that I am checking my new task off as complete. Almost as if I just added it for record keeping.
Is there an 'enter' button somewhere that I am not seeing?
We thought it's more intuitive than a complex floppy disk icon (especially as floppies have been abandoned a long time ago), but we'll consider changing it in the future and you're welcome to add a request for such change to our Votebox: http://todoist.com/Vote_Android/
