Minimum window width

Hi @sim
see here:

Scaling window problem on portrait monitor

The problem is that the Dorico project window’s minimum width is too wide for your display, so it’s being forced to its minimum width when you interact with it. We’ve made some changes in Dorico 5.1 that should alleviate this problem, so please give this a try in the new update when it arrives.

You can temporarely augment the definition of your screen, maybe?
