For a personal start page such as BentoBox, the value lies in a repeatable daily glance. Recreate your actual bookmarks, widgets, and layout in a candidate, then use it for a normal workweek. Count the clicks required to reach common destinations and notice whether the page remains usable on a phone or a slower device.
Check how settings are backed up and restored, whether embedded widgets expose sensitive information, and if multiple browsers stay consistent. A dashboard with more widgets can still be worse if it loads slowly or buries the links you open every morning. Keep the old setup until the new one survives a clean-browser restore.
