It can be very useful if would be a feature to view all animation keyframes on scene. this shortcut will open all groups. This feature can be more comfort control of delayes between keyframes. I know I can open all groups into parent group click on arrow with alt. But what I need if I haven’t parent group?
Thanks for the request! It sounds like it would be either useful to filter out elements that do not have keyframes and/or propagate some sort of display of keyframes up to the group level so you can tell a closed group has animations within.
