I've been mostly away from IMCDb for a month now (I've started a part-time job) and am quite surprised by the sheer size of the admin page ! I'm not a tech guy so I don't know why a "small" smartphone screen needs a page that looks enormous on a 15-inch 1920x1080 laptop display... which I don't like anyway, as text and icons were too small for my eyesight when I first got it, so I've had to add a +25% zoom to make things legible. And I guess that zoom doesn't help about the page size.

Anyway, the zoom adjustment and Reduce space between rows option have helped.
