Blueprint Assist (5.7) for Unreal Engine

Numerous keyboard shortcuts: The plugin adds shortcuts for all node creation and modification functionality which were previously only accessible through the mouse. No more right-clicking every time you want to create a node!

Additional quality of life features and improvements: A number of new features and functionality are included in the plugin.

I highly suggest you also download the free AutoSizeComments plugin. The BlueprintAssist plugin does not handle comment nodes. AutoSizeComments fixes this issue and comes with other useful functionality.
