**Feature Request** All symbols in EasyEDA Libs should have default simulation models associated with them: >Diode: EB91_DM >Triode: ECC83_DM >Tetrode: EF86_DM >Pentode: I think we should remove the 5 pin pentode symbol from EasyEDA Libs and just put it under `More Libraries...`. See below. **Why we should remove the 5 pin pentode symbol from EasyEDA Libs and just put it under `More Libraries...`:** The tetrode symbol is used for **all** available pentode models because **all** the so-called pentode models in fact only have 4 pins (Anode, Grid1, Grid2 and Cathode). This is because the pentode models all assume that Grid3 is connected to the Cathode and so the tube actually operates as a tetrode. No pentode models have yet been found suitable for use with the 5 pin pentode symbol.
