Request: Preset dropdown left/right aligned

[dja]

Not meaning to add more params than necessary, but it would be great to choose if the preset menu button is left or right aligned. I've done this in my own fork, if you want to take a look: https://github.com/danieljacobarcher/calendar

@danieljacobarcher is this not worth then submitting a PR so @tyvdh can look at it easier & review it with you to get it merged back into the project?
