Multiselect keyframes would save so much time

The introduction of the drag-to-select feature has been a godsend, thank you so much to the community for following through with that. Eases too, and the recent dropshadow filter, have made my life so much easier. There’s another thing, however, that would speed up the editing workflow dramatically.

Some context first
I often have keyframes for certain animations across many different filters that I reuse a lot. I’ll typically have things for animating the clip in, and animating the clip out. Animating the clip in never needs to be altered when pasting onto another track, but when I need to change the length of the track, it gets very exhausting needing to drag the start of the transition outwards to a desired position, and then dragging the end to the new desired position to be exactly [x amount] of seconds after that new starting position. Doing this across multiple filters gets very time consuming.

The solution
If it were possible to select many keyframes at once, and drag them together, that would be a huge time save. Further, if it were possible to view multiple parameters across many filters (I’m very rarely using a tonne of them since having many filters creates unusable lag, so visual clutter isn’t so much a problem IMO) that would make it even easier.
If someone knows how to do this, I’d really appreciate if it could be looked into.
Another tiny thing while I’m here: it’d be great if there could be a checkbox in the eases menu so I can easily remember what kind of ease I’ve used on a keyframe.

Cheers for all the great updates recently guys! I look forward to seeing the results of y’alls cooking in the future.
