I totally agree that it would be, indeed, useful.
A lot of other similar posts, like this one i did recently:

Or generally others with “wish”:

The hope is that David find some time in future to add them, IF it is worth.
Grasshopper 2 is under development and many small features can be already planned and/or the structure overall will change so a current idea for GH1 doesn’t “fit” in GH2 … maybe.
But probably the focus on the development is mainly on the reliability of the functionalities instead of the “extras”.
If i would be asked what i prefer between a more solid mesh slicing/intersecting math or a dozens of extra functions (for ui and such) , i would prefer the mesh thing.
Like, on your car would you prefer to add air conditioning or a more powerful engine?
There is the “serengeti” tag in this forum, which is more related about the development of rhino and grasshopper.
I don’t remember often to visit that category, but you might find it interesting and have a more detailed info about the overall situation.
This is all from just my personal and partial view of the situation, i can be wrong in many aspects.
