Remove the 4-widget limit on the horizontal stack

I would like to request removing or increasing the 4-widget cap on the horizontal stack.

Allowing more widgets empowers users to build a more comprehensive productivity dashboard accessible at a glance. Because the horizontal stack is only interacted with intentionally, removing this cap perfectly fits the "Independent" guideline: it does not add any complexity or UI clutter for users who only want one or two widgets, but it significantly boosts utility and productivity for those who need access to more tools.
