It would be fun to learn about the ideas/opinions that people have that could help advance pinball. Face it pinball hasn't changed much in the past 20 years.
RFID READERS AND CHIPS
I keep coming back to the idea of integrating some form of technology that could detect a specific pinball on the playfield. This could widely increase the amount of things you could do with gameplay. Imagine getting a 5 ball multiball but the shots only get counted if a specific ball goes through a specific ramp or hits a specific target. Instead of having optos detect the ball....they are replaced with RFID readers.
I know this is a daydream but not sure if produced on a mass scale if this would be feasible.

Readers wouldn't have to be placed on the playfield, but could also be placed under the playfield. Additionally each reader could have their own frequency and range (2-4cm). So they would not conflict with one another. They are relitively cheap....and I assume if purcahsed on mass QTYs they would be even cheaper.
Imagine for instance having a Fast and Furious pinball with a stakeout spot on the playfield. The spot is occupied by a "tagged police" pinball. When triggered the ball gets launched onto the playfield during gameplay. Your goal would be to get pinball "tagged turetto" onto the container truck. But if you shoot pinball "police" in the container then you lose the mode and have to restart and lose points.
I can think of a million scenerios of this and you greatly evolve pinball gameplay.
Obvisouly pinball folks would have to equip themselves with a RFID encoder. Balls come pakacaged uncoded. You place the ball near the encoder and enter the code for each specific ball and insert them in your game.
