I thought of a few small changes and additions that (hopefully) wont break any old saves, but would be nice to have.

Modification:

PUMP:

PUMP will now have 2 modes, Regular mode, and Filler/Emptier mode. The 2 modes will be dictated by life.

Filler/Emptier mode (Ill call it F/E bc its a mouthful) will work like VENT by adding its current temp converted into pressure to the surrounding area.This will work both ways, for example if the PUMPs temp is -10C it will reduce the surrounding areas pressure by 10, if the pressure is 40, then it will be 30. The affected area is controlled by TMP, 1 will only affect the pixel the PUMP is on, 2 is a 3x3 grid with the PUMP at its center, 3 is 5x5, and so on. The interval between filling/emptying is controlled by TMP2, 1 second is 10 TMP2. PUMP in F/E will reduce pressure by its current temp in a square size TMP every TMP2/10 seconds.

Regular mode will mostly be the same with the current PUMP, but the properties of TMP and TMP2 will be borrowed from F/E mode, except if the TMP, TMP2, and TMP3 is 0 it will work the same way it does now. TMP3 will be used to subtitute as the temp from F/E mode, as temp in Regular mode is used as the target pressure

New element:

WIRE: Wire, useful for electronics.

An element which will be useful for electronics. WIRE will only transfer SPRK to a wire of the same CTYPE. TMP dictates whether the wire will transfer SPRK instantly like INST or not. TMP2 dictates the SPRK gap distance, 0 means it will not transfer SPRK across gaps, 1 mean it will only transfer across 1 pixel gaps, and so on. TMP3 dictates whether or not it will transfer through materials, 0 means it cannot transfer through any material, 1 means it can transfer through any material except INSL but only if theres only 1 pixel blocking it, 2 means it can transfer through any material except INSL of any width, 3 means it can transfer through any material including INSL but only if theres one pixel blocking it, 4 means it csn tranfer though any material including INSL of any width

Those are all of my suggestions

EDIT: After rereading the banned element list, i removed the suggestion for Heat Pump

 Wire will be an element like PSCN or any other regular element
