For now I place them like shown in the picture at each OP Amp or IC.
My questions starts now: Since all capacitors share the same net, how can I make sure that the reference designator in the schematic later mach up with the physically placed capacitor in the layout. Is there any other way then looking them up in the schematic and then search for the right capacitor in the layout? Or is best practice to place them and later rename all components with this external tool for Kicad. LINK
