I looked at that jira link and didn't see an issue for my suggestion.
The one thing I love about the default interface is filtering recipes by reagent. For example if i have lots of felweed and want to see what I can craft with it. Type in felweed and it displays only the recipes that use that reagent. Unfortunatly neither Skillet or ATSW do this. They only filter by recipe name.
Is this a useful enough idea to be put on a list of future enhancements?
I've recently changed the recipe filtering so that it checks both recipe names and reagent names. In your example, typing in 'felweed' will display any recipe with Felweed in the name, or in the list of reagents. This was filed as http://jira.wowace.com/browse/SKL-32
I'm planning on expanding the filtering options in future versions, but doing that right is going to take a bit more time than I have at the moment, so I've pushed it to a future version.
