Would be fantastic to show a count of selected nodes somewhere within the editor. Great if you are needing to know how many nodes in the system- or how many nodes you have selected, for any reason.
Similar to how finder shows how many items are selected. Need only be a small dialogue that is in the center of menu bar? Maybe this could allow for a feedback dialogue area? So as in other software (I am thinking of GIMP) it lets you know what you can achieve by pressing different buttons etc)?
Positioning of dialogue is not important in this request, simply that it allows feedback as to how many items are selected.
Could also show selection dialogue about cables if people think that is also helpful.
