  1. Highlight selected component ?

  2. Add misc operations: poles, zeros, etc.

  3. Show current through component. For wires this is tricky and will require some Lcapy magic. Need to sum all the currents coming into the branch node. This requires recursion if connected to other wires. Stop if reach one of the branch nodes

  4. Redo...

  5. Move components

  6. Rotate components? Perhaps just delete and re-enter but lose attributes unless clever

  7. User levels to hide many options

  8. Add numerical analysis

  9. Add node in middle of wire? Need to delete wire or split into two.

  10. Draw nodes after drawing cpts (for port nodes)

  11. Close/quit

  12. Add labels, voltage labels, current labels to cpt attributes

  13. Connect opamp negative output node to ground

  14. Make Lcapy more robust to nodes being changed when node positions are defined

  15. Add frequency and phase to AC sources

  16. Fill open nodes so not transparent to wire underneath

  17. Fix Lcapy to simplify condition expression for t >= 0

  18. Reposition component labels to match circuitikz

  19. Fix fullscreen

  20. Fix transistor menagerie if base/gate offset

  21. Add voltage, current, and flow labels

  22. Add generic labels

  23. Use suffixes for component values (u, p, M, etc)

  24. Handle exception when creating circuitiz image

  25. Fix circuitikz image creation to use node positions

  26. Fix invert for opamp

  27. Add label position modifiers

  28. Add U components

  29. Check if opamp has node 0 as output reference and warn if have no other node 0.

  30. Add mutual inductance (could associate with a transformer but would need to output two inductors and a mutual inductance; this will be hard to interpret). Probably need to modify TF in Lcapy to have arguments for the two self-inductances and the coupling coefficient. In the interim, have a coupling dialog (edit/couplings) that specifies the couplings, e.g., L1 L2 1.

  31. Select connections

  32. Remove opts field from components

  33. Better labels for transformers (show turns ratio)

  34. History of operations (perhaps convert to Python script)

  35. Fix label_pos for rotations

  36. Add value_pos

  37. Fix transistor drawing

  38. Show symbol pins for debugging

  39. Add network synthesis

  40. Stretch transformer
