Themes, layouts, and styling objects on a slide

The Design panel on the right of the deck editor turns a blank slide into an on-brand one fast, and the per-object controls give you the fine styling you'd expect from a real design tool.

Themes
• The Themes row lists a set of built-in palettes plus — if your org has set brand colors in Org Branding — your own brand theme first.
• Click a theme to adopt it as the working palette: it recolors the current slide background and sets the accent, text color, heading font, and gradient color so anything you draw next is already on-brand.

Slide layouts
• "Add slide layout" inserts a new, pre-composed slide (title, title + content, section header, etc.) rendered in your first theme — a fast way to keep a deck visually consistent instead of starting every slide blank.

Per-object styling (select an object first)
• Opacity — a slider from 0–100% to fade any object.
• Gradient — toggle a gradient fill and pick the end color; great for shape backgrounds and section panels.
• Drop shadow — toggle a soft shadow to lift an object off the slide. (Gradient and shadow don't apply to raster photos.)

Arrange (z-order, flip, group)
• Bring to front / forward / backward / send to back — control which objects stack on top.
• Flip horizontal / vertical — mirror an object.
• Group — select two or more objects and group them so they move and scale as one; Ungroup splits a group back apart. Groups survive save, export, and PowerPoint import/export.
