PR Summary

• Updated Stylesheet The style rules in the toolbar.css file were edited, this affects how the toolbar appears.
• Changes in Toolbar Visibility and Transparency The settings for how visible and transparent the personal toolbar is were altered.
• Adjusted Transition Effects The animation effect showing the shift between the toolbar being compacted and fully visible was refined. This could lead to a smoother and more visually pleasing experience for the users.
