P: Allow a much larger Filmstrip in Develop for dual-monitor workflows

I use Lightroom Classic for high-volume professional photography and regularly cull several thousand images in a session.

My workflow is to remain in the Develop module with the Crop tool permanently active. I move rapidly through images using the Filmstrip, adjusting the crop where required before moving immediately to the next image.

I use Lightroom's Secondary Display on a calibrated 27" monitor, which displays the current image full-screen. This means the large central image area in Develop on my MacBook is largely redundant, what I actually need on the primary display is the Develop controls and a much larger thumbnail Filmstrip.

Currently the Filmstrip can only be dragged upwards to a fairly restrictive maximum height.

It would be extremely useful if Lightroom allowed the Filmstrip to be resized much further, or offered a Develop workspace consisting primarily of a large thumbnail browser plus Develop controls when Secondary Display is active.

As a real-world example, my normal workflow can involve reducing around 5,000 images to 250 finished, cropped and edited photographs in approximately six hours. Larger thumbnails would materially improve the speed and accuracy of that workflow.
