Let the Pickwhip twirl down layer items on hover, as the Project Panel would if dragging to a closed folder

Hey! When using the Pickwhip to reference things while writing expressions I frequently forget to twirl open the property I intend to select. This usually means that I have to exit writing the expression where I am, twirl open the property in the timeline to make it visible, then resume the expression writing / pickwhip and carry on.

It would be a good quality of life improvement if while dragging the pickwhip, hovering over a twirled-up item would unfold it. The closest analogue would be dragging a file into the Project Panel - if I hover over a closed Project Panel folder for a second or so it will twirl open.

I’d initially suggest that this would only be useful to have on the Expression Pickwhip - there seems to be limited functional use for adding it to the Matte or Parent Pickwhips.

Perhaps a longer timeout when hovering over a layer itself compared to hovering over a layer property might be useful - that way users would be less likely to trigger un-twirling when simply selecting top-level layers, and would make the initial twirl open feel deliberate. A quicker activation when hovering over an exposed property would make sense, and be helpful if there are multiple levels to get to before exposing the property or control to be targeted.

The use cases for this happen to me most often when referencing Effects for expressions. If I remember to do so I will pin open the effects panel on the appropriate layer, but I frequently forget to do so, and this update would mitigate that requirement for pre-thought, and allow more spontaneous experimentation while writing expressions.

TLDR - Let the Expression Pickwhip twirl down layers when dragged and hovered over layers and properties. Adding this functionality to the pickwhip would be really valuable - it would help stay in the flow, reduce the amount of clicks needed per task, and make it easier to experiment.

Cheers!
