The reminder feature is an interesting idea. However, I think aligning the skeleton's pose with a specific frame of an animation using the slider added in 4.3-beta might be easier.
You can create sliders from the New... button in the tree view when an animation is selected. Specify the frame you want to reference in the Frame field, and set the Mix value to 100 to reuse the pose of that animation in another animation. This allows you to automatically apply changes made to one animation to another when you change the pose of the latter.
You can animate the Mix value, so setting it to 0 releases the constraint to another animation pose.
If you haven't tried it yet, we hope you will give it a try.
