Hi Kovid and team,

I'm a long-time user of Calibre who recently reopened the ebook viewer after a long time — and I was reminded of how powerful the software is. However, I also remembered why I initially found the viewer somewhat uninviting.

The default layout stretches text across the entire screen width, which can feel awkward and hard to read — especially on modern wide monitors. Many users (myself included, in the past) may assume that the viewer lacks polish or customization simply because the default experience is visually overwhelming.

Only after diving into the preferences again did I realize that setting a maximum screen width for the text column (e.g., 600px) and keeping height as 0 vastly improves the experience, providing a clean, centered, Kindle-like reading layout.

Suggested improvement:
Set the default text column width to around 600–700px.

Leave height as 0 (full vertical use).

(Optional) Enable minimal UI or fullscreen (F11) on first launch.

These small changes could significantly improve first impressions and make new users more likely to adopt the viewer as their primary reading tool.

Thank you for your ongoing work on Calibre. This project is a gem, and I deeply appreciate your dedication.

Best regards,
A happy and now properly-centered reader. 😄
