This so much. I have a three days a week home Office deal, and I did Not, We, Fr for some time and it sucked. Monday I just could not find a proper start for the workday, which in the end translated to doing more work in the evening. Same on fridays, where I just did not find a proper cut to end the work day. So bad it even went into Saturday mornings. Now I do Tu-Th as home Office days, which works amazingly.
Scientist here, a lot of my job is writing texts with references to other literature of the field, or reviewing such texts (or PowerPoints). Main screen has the document open, the other is actually in portrait format and has gazillions of open pdfs on it that are relevant to whatever I’m working on. I had to get this setup for working from home because productivity dropped immensely with only one screen.
