#Button alignment Left aligned buttons do have several advantages:

• fits forms structured with left or top aligned labels
• no guessing where to position the button on a wide screen
• works well on mobile

#Button prioritization

• assuming most users complete the entire process in one session Next is the primary action and should be highlighted as such
• Previous is secondary, i.e. should be grey (or even a link)

#Save draft

• Can be a nice and convenient feature if the form is very long or there's a reason why users would want to save
• Save also requires some thought: how do users save, what is displayed during saving the input and what is shown as a confirmation? Can they save again? How do they access a saved form afterwards?
• If you can afford it I'd suggest to consider auto-saving the form (see composing emails in Gmail as an example)
