Column Layout Support for Dashboard Organization

We need the ability to create flexible columns in our dashboard, similar to Notion's layout system, where we can:

• Drag and drop content into different columns

• Resize columns freely

• Organize our workspace with multiple columns side by side

• Move between different apps/tools within these columns

This would help us:

1. Keep related content grouped together visually

2. Create custom layouts for different workflows

3. See multiple tools/pages at once (like having tasks in one column, notes in another)

4. Better organize our workspace instead of switching between full-width pages

Think of it like Notion's drag-to-side feature that creates columns - super useful for building personalized dashboards!

Thanks for considering this feature!
