Ability to choose first day of the week
Let the user override the first of the week. For example, my phone is using us language but I'm french so I would the first day of the week to be Monday.
I'm so sorry, my phone view is terrible, I meant to add a comment, not to flag the suggestion. It is a really great suggestion and I'd really love to see it done as I keep assigning my tasks to wrong days because of Sunday being the first date.
