Quality Of Life addition to animation curves modifiers

There could be additional buttons to the "restrict frame range" section The buttons would take current frame and paste it into the box And when it comes to "Blend In" and "Out", the button would calculate distance between "Start" and "End" values and current frame

So if, let's say, "End" is on frame 260 and the current frame is 250, the Blend Out value would be set to 10

It seems like a more straight-forward way of working with animation as we usually don't think in exact frames, we think in moments at which something should be happening. And it undoubtedly would spare a bunch of copy-pasting and tweaking
