New Tooltip UX:
In-app tooltips have been re-styled and most now have the "Chat to learn more" button.
The button automatically sends a prompt to in-app copilot, providing instant response and assistance.
Future plan: Turn this in-house feature into a deployment option available for everyone.
CustomGPT.ai for Teams quality-of-life updates:
A new Team Administrator pre-defined role has been added, which mirrors the existing Administrator role with the additional privilege of being able to create new member roles.
If there is more than 1 team member who created agents for the team, their name is now displayed on the agent's card on the Agents page, and there is a new dropdown to filter by author.

New major UI feature - Agent Style
All elements inside the agent now have the same edge roundness.
Three options are available: Sharp, Soft, Round. Old agents have access to the Legacy setting as well, where everything stays as it was.
This setting also affects outer edges on all deployments - including Embed & SGE.
More agent window size options
New window size added - Compact - preserves the width of the chat area available on the old Window setting, but with greatly reduced white space around it.
The old Live Chat Window setting is now called Focus.
Compact is the new default for Live Chat deployments.
Both Compact & Focus are now available as options on Website Copilot and Instant Viewer as well.
Existing agents are unaffected by the change.
Updated default Live Chat Bubble and SGE deployment dimensions for new agents.
New default layout for new agents:
Agent avatar is now visible by default, while User avatar is hidden.
To accommodate this, avatar visibility is now a Standard plan setting (previously was Premium)
The Fresh color scheme has been renamed to Adaptive.
Border has been added to the Starter Questions box to better accommodate the new default white background.

All deployment options now have the "Try it out" button which instantly shows that very agent and how it will look when deployed on the website.
