How to extend spreadsheet animations to a certain point? How to easily view selected column's animation frames in spreadsheet?

[Michael Chandy Thomson]

Hi again, two questions about using the spreadsheet and graphs.

First one is, how do I cut of a repeating animation at a certain point? 

I've got a good animation curve going, I'm pretty satisfied and I'd like to repeat the movement. At a certain point I've decided it's enough and create a keyframe there. Problem is, the repeating curve (represented by a dotted line) is just completely flattened. Here's my work, my play head represents the point at which I'd like to stop the animation.

End of first question.

Second question is how do I get OpenToonz to show the selected column's animation values in the spreadsheet editor instead of everything?

It's pretty difficult navigating the folder structure, hiding everything and then finding your selected column.

That's all, thank you!
