Add functionality to both toolbar and settings flyout

Question

I have some settings in my app (e.g. set a timer). Is it bad practice to add a button for this in both the toolbar and the settings area (Settings Charm)?

Is there a best practice as to what goes where?

Answer 1

According to design guidelines, all settings should be under the Settings charms

Answer 2

But e.g. a set timeout function in a app. Should this be in the toolbar or as a settings?

Answer 3

Is it an application wide setting? Something that the user would likely set once and then leave alone? If so, then settings are appropriate. If it's a more local setting that would be scoped to a single page, changed frequently, etc. then an appbar button would be better.

It's not clear what exactly you mean by "set timeout function", but if you mean setting a single timeout that will rarely be changed then the settings pane is appropriate. If you are setting a timeout for a specific action then an appbar button may be more appropriate.

Take a look a the User experience guidelines in the Guidelines for app settings .
