Progress of WKD in different products

This page informs about the progress of WKD and its usability in different products. The page also contains links to issues so everybody can see if a feature is already in work. Feel free to add information and to create issues for your favorite product.

Here is an explanation of some columns:

• Supports WKD: There are two stars because the draft for the WKD standard contains two methods - the direct and the advanced method. If a product supports one of these methods it gets one star. If it supports both methods it gets two stars.
• Usability of WKD: In a bachelor thesis there were developed criteria for the usability of WKD in a products. Each fulfilled criterion will be represented by one filled star. One criterion concerned if a product supports WKD. Because this criterion is in a different column on this page, here are only 12 steps that can be reached.

Note: The list of products will be sorted alphabetically.
