//General features, sorted by most useful//
ability to select multiple nodes and change multiple parameters simultaneously, so long as they're the same parameters.
tool options to distribute nodes evenly, horizontally or vertically.
dynamic input node (input that accepts grayscale and color, like on most atomic nodes)
smooth min mode for voronoi nodes
atomic histogram equalization node
atomic gaussian blur Filter (the blur HQ node is a favorite among most users, so why not make it an atomic node? having 2 separate nodes is a burden for something people use very frequently, and blur HQ is rather slow, in my humble opinion. a fast atomic gaussian blur would be an awesome addition)

//Pixel/Value Processor Features, sorted by most useful//
mipmaps for sample gray/color, both manual and automatic. this is my #1 suggestion/request. It would open up so many doors.
multiple outputs for custom functions, and any new atomic nodes that require multiple outputs.
automatic scalar vectorization. Would eliminate the need for scalar nodes, i.e. scalar multiplication, etc.
ability to expose parameters on sample gray/color as inputs. if mipmaps are added, this would be especially useful. No longer would one need to use multiple sample nodes to switch between input images, filtering modes, and wrap modes. additionally, having the input image parameter exposed would make certain things much easier. for example, one could easily create an atlas function with a while loop)
system variable for the original node size (example: if your node has a size of 256x256 and you increase the size by a factor of 1, making it 512x512, this variable would still return 256x256)
system variable for texel size (1/size)
system variable for total number of input images.
system variables for Pixel Size, Pixel Ratio, and Random Seed (more so Pixel Size and Pixel Ratio. these are only used on atomic graph nodes, which is kind of a waste)
dynamic number of inputs (up to 16 or more) for all arithmetic nodes, and minimum/maximum nodes. (similar to how the pixel/value processor and fxmap have a dynamic number of inputs. By default, only have 2 inputs visible, and each additional input would be visible only when you're dragging a wire. example: add 10 values together with a single addition node)
default input values for nodes (example: the multiply node would have a default value of 1 for both the A and B inputs). In addition to this, make the default values directly modifiable on the node, i.e. no need to even click on the node. this would make any user's workflow much faster and smoother.
access to atomic random node's position.
different precision types. would greatly help with optimizing.
unsigned Integer data type.
matrix data type (not extremely necessary, but would be a nice addition)
arrays (useful for all sorts of things, though i understand this may be difficult to implement in an intuitive, flexible way. Nuke has array nodes, so it's probably doable)
