Widget Visibility Without Jetpack
Sometimes you just want to display different widgets per page. Jetpack has a great module for this, but taking on all of Jetpack can be a lot if you just need one thing.
This plugin offers just the Widget Visibility feature, without bringing all of Jetpack along for the ride. Very helpful on a recent client project, and part of a trend I can see developing of atomizing some relatively easily isolated Jetpack features. Have a look!
