Regarding new noise functions, we do intend to add more at some point in the future. But we don't have a specific release date for that.
One of the things about TG's noise functions and their implementation to-date is they're not as simple as the basic forms you might often see out there, and this is in several respects. First, they've been setup and tuned specifically to work well in TG, both in terms of the rendering process, as well as the actual usefulness of the output (think for example of the way Lead-in scale vs. Feature scale vs. Smallest scale works). Second, additional controls and functions such as warping, etc. are usually added. Third, in some cases controls have actually been simplified for ease of use or removed due to implementation or compatibility concerns.
So when we contemplate adding new noise functions, if we're to make something that for example adds in to the Power Fractal, it has more considerations than just adding a simple off-the-shelf noise function. That being said, we're certainly thinking about simpler options as well, both for reasons of implementation speed, and allowing more simple use (think of a simple Perlin Generator, or the Voronoi Function Node except without requiring an input). But simpler is less powerful too. As I said, we're considering these various options for the eventual implementation of more noise functions, which we do have planned.
