[FEATURE REQUEST] See what cells are being executed

[carrapaz]

Hi my notebook is growing quite big and has many variables, I apparently assigned some names in global scope to more than one thing (ik rookie mystake xD) which made the performance plummet and maybe broke something somewhere idk...
i was wandering if it is possible to see what cells are executed? bcs i have the feeling one of my variables is calling a function!? just because the variable and the function has a parameter with the same name but idk how to confirm this.
maybe it would be cool if clicking or ctrl clicking in the status, evaluating cells showed which ones have been evaluated

binding the slider to S1 6 cells 250ms:

binding it to S13 4 cells 23ms:

almost 10 times faster! so i would like to figure out what those cells are since i used S1 in functions due to lazyness but nowhere else is the same scope just as a parameter to pass inside the function so why is the cell called?
this is the notebook:

thanks :)
