Wishlist, simulation: OP simulation labels

Description

OP sim results should be visualised on a schematic for better user experience.

"new label, to be put on a net connection, as a location for the operating point data presented in the circuit schematic automatically after simulation"

"switch to enable operating point data shown on all net connections in the circuit schematic automatically after simulation"

"It is common to print DC bias point voltages and currents on the schematic for each net after simulation. This is not possible in KiCad now. Often I see it as floating text box with a line to the net/component, or as a small bubble embedded into the net. This is quite helpful for voltage dividers and other simple circuits where only DC voltages and currents are needed since it allows performing the simulation and seeing the results in one place (not having to go to the Simulation window). A way to re-run the simulation from within Eeschema would be needed to fully realize this item."
