My idea is add a new item as I say on title. It will show a clock that show time active of dimensional phase-out, damage amplifier and shield. Also it will show delay time of mines and poultry payback
I think ſomeone already ſuggeﬅed this.
It is already suggested: Timers for Phase-outs and Amplifiers
I base from @OneWingLunarian idea but it is a mountable item
