Currently the symbol slotting functionality struggles to handle power pins well (at least that is what some brief googling showed). A recurring theme with regards to slotting is that power pins show up on all the slots, e.g. dual/quad opamp which has a single set of power pins for each of the opamps - if the power pins are visible and not embedded they show up on each slot.
Some people have a problem with this from a "style" perspective (it is visually different to other CAD packages). A slightly more important issue is that if the pins are left unconnected (for more readable schematics) it messes with the DRC checking, which expects all pins to be connected (and possibly with the netlister?). I had a thought which might solve both of these issues. If a special character was defined for slotting which indicated that the pin should be excluded from the schematic that character could be used in place of the power pin slot. So for a dual opamp with slots defined slotdef = 1:3,2,8,4,1 slotdef = 2:5,6,8,4,7 it would become slotdef = 1:3,2,8,4,1 slotdef = 2:5,6,N,N,7 if 'N' was the special character. The 'N' pins would then be ignored by the rendered, DRC, netlister, etc. Maybe even just slotdef = 2:5,6,,,7 would work too. Maybe this has already been done? I have absolutely no idea how the internals work for rendering the symbol and passing the info to the DRC and netlister. Just thought I'd share the idea in case anyone is interested.
