I am just finishing it up

This PR blends the selected keyframes to an ease-in or ease-out curve.

Code looks good to me (just one small nit).

However, it's not clear to me what the use case is for this...? I'm sure I could think of a contrived case where it would be useful, but I'm struggling to think of any likely situation where this would be what I want. I guess that goes for #110567 as well.

But I could certainly be missing something.

Might make sense to move the declaration of y_delta inside the for loop below, closer to where it's used.

The consensus in the module meeting was that this is useful. Just the one nit, and then it's ready to land.

Just some very minor nits in a couple comments. Other than that, looks good to me!

Missing period. I also briefly found the use of the word "noise" here slightly confusing. Not a big deal at all, but maybe change it to something like "The curve doesn't do what we want beyond our margins...".
