Remarks

Customization

In Windows 8.x, a non-static Hub Section would have a small chevron next to that section's title to indicate a link to more content beyond the sample in the visible screen area. The chevron has been replaced in Windows 10 by a link with the text "See more." While functionally identical to the old chevron, the see also link can be easily modified by changing the text in the ui.resjson resource file for the language of interest. Simply locate the line "seeMore": "See more", and change the text "See more" as required. This feature also facilitates easier localization.

Requirements

Minimum WinJS version	WinJS 2.0
