Ramp Manager is a Python-based HDA which allows you to save colour and spline ramp presets for reuse across Houdini sessions. You can forward ramps from the asset onto any other node and perform some common ramp manipulations. I've personally used it to save visualisers (heat-map, blackbody etc), spline ease functions and many project-specific colour schemes. You can download it as part of the Aelib library here: https://github.com/Aeoll/Aelib Or on its own here: https://goo.gl/j47nrI

UPDATE - The new PolyPath SOP in Houdini 16 supercedes CurveJoiner, which has now been archived. Aelib is a library of Houdini assets, presets and scripts. It contains more than 50 HDAs which add functionality for geometry creation, deformation, curve tools, SOP utilities and more. This video previews a selection of tools for manipulating polylines and other curves. The library can be downloaded here - https://github.com/Aeoll/Aelib
