There is a humanizer here. Why is there no anti-humanizer? Purely practically it would be more useful. If you still don't understand the point, it's very simple. This is a function that aligns selected notes to a selected grid. It would be very useful for at least one person - me. Сould the developers add it?
This is confusing since placing notes already aligns them to the grid, and if you humanized a selection you could just hit ctrl+z to undo it. Unless you mean you wish to have more advanced grid options, you could just use the inspect tool > console > type "Grid=X/X", and you're good to go. If not either of these, elaborate.
As Isaac said, placing notes already has them aligned and you can snap misaligned notes to the current grid by clicking on them, and you can reset the note volumes with alt+0.
If you do manage to get a lot of misaligned notes that can't be fixed with ctrl+z, here's a little console script to re-align them:
tweakNotes(n=>n.time = Math.round(n.time * grid) / grid)
