These are features that may already be in Blender, but I am pretty new and dont know if it is new or not.
Anyway, Lets get started with points adding:
I imported a 3d file, but it has no points, its just a robot, but it has no vertices. I would need to add points to add vertices. IS there anyway this feature could be added?
Line tool: A tool that would just draw lines from one point to another, and then you could connect other lines. Sort of like point plotting. This would be good if you import an image and you want to trace it from all sides. Sort of like photo modeling.
This brings me to the modeller:
Would there ever be a feature like in photo modeller, where you can import an image and have blender model all the sides of it easily for you?
A tool that could push certain vertices and points forward and out. Good if you are making a face and you want to add more details to the cheecks.
