Cydia-SearchNC is a new Cydia tweak which allows you to search tweak directly in the notification center without launching Cydia. You just need to type the name of the package you want into a dialog that says “Search on Cyida”, press enter, and Cydia opens with a search for whatever term you entered.
Cydia-SearchNC was also made with iNtelliscreen X and Lockinfo in mind, so if you prefer you can have the search widget on your SpringBoard or lockscreen. Widgets have a hit-and-miss reputation with iPad support, so if you use the iPad, you will be happy to know that Cydia-SearchNC happens to work perfectly in the iPad’s notification center.
Cydia-SearchNC is available in the ZodTTD & MacCiti public repo which is a default repository on Cydia. You can also find this tweak on Cydia’s BigBoss repo.
Note: The widget is free and requires iOS 5.
