Quicker method when creating nodes

I would like to propose a quicker method when creating node in geometry nodes. I just make one example, but i think you could extend the idea to a lot of nodes. If you have a node tree and you create e.g. a new math node from an output from another node by dragging, let's say it is an add-node, and you want to add 2. There is only one field free in this case. Instead of clicking first in the value field, i would like to just being able to enter a number (2) and it would be filled.
