Swipe up and down to change the current view
I almost ever use the week-view but sometimes I have to change it to day-view and hate to push the menu on the top left and do the change just to see more information of one particular day. It really sucks.
Instead of doing this, I'd like to swipe down and accordingly to the day I started to swipe from, the day view of the day I started to swipe from will appear. Swiping up from the week view will enter the month view. Swiping up again will reenter the day view of the selected day (starting point of swiping). Swiping Up again will re-enter the week view of the week the previous day is in, so there will be a loop functionality.
Up-swiping and down-swiping are not declared as functions yet, so it would be great to assign them as described.
