often times I like the be able to fluctuate a parameter further. like fuzzy dab

 ![fuzzy d time curve](https://krita-artists.org/uploads/default/original/3X/5/6/5608be7141b14e16a435a8b561515404c28a78bc.png)

I could also see fade and speed work.

it would change the fuzzy dab intensity ovver time.

If I’m understanding you correctly, you can already do that. By default, the values of different sensors are multiplied (can be changed via the dropdown) by each other. So all you need to do is activate the ‘Time’ sensor and make your desired curve, and it will scale the other sensor(s), in your case ‘Fuzzy Dab’.

yes but the difference is if I had made edits to like pressure and I didnt want that to be affected by time,  
so like restrict time to just fuzzy dab

Ah, I see. This could be useful indeed.

It’s like the Mod Matrix on a synthesizer: Many allow you to just say ‘modulate x by y’, but the more advanced ones let you gate said modulation by a third parameter. So ‘modulate x by (y \* z)’. I really miss this here too, so great request!

Neutral point strength over time is another value that would be very useful to adjust.

 ![neutral point over time texture](https://krita-artists.org/uploads/default/original/3X/b/1/b15498a43c617363eb49b34a880cb7a23c6035da.png)

it can make a pattern standout more at start of stroke.
