Just to add to this topic, that recently I moved from Studio One to Cubase after almost 10 years with the former. And the last straw was exactly this, that I can't scale the UI, while in Cubase I can (I'm using additional +50 scaling, I'm in my 40s, so, you know...).
Small unexpected thing to decide in which DAW to produce music, but here we are.
After spending a few weeks in Cubase and then loading Studio One, I was asking myself how I could even work there?
Will I return to Studio One, if/when UI scaling is implemented? Maybe. But I certainly won't until it's done.
