Using Dialogs

Common User Interface Guidelines state:

• Use dialogs only for actions that deviate from the primary task flow.
• Any dialog pauses the interaction of an application with the user.
• Dialogs should ideally be designed such that they could be ignored altogether, without disrupting the user's ability to complete their job.
• This implies that it is best to minimize the use of dialogs and emphasize direct manipulation within interface
• However, there are times when Dialogs cannot be avoided.
• Request further/alternative input
