Added smooth transitions for hover and click interactions.
Improved text spacing and readability.

Palette Modernization:
Redesigned the palette with a clean white background, rounded corners, and soft shadows.
Added smooth fade-in and slide-down animations for opening and closing the palette.
Introduced hover effects for palette items and improved header styling.

Loading Spinner and Status Bar:
Added a loading spinner with a smooth animation to indicate loading states.
Introduced a status bar at the bottom of the screen to display the app's current state (e.g., "Loading...", "Connected", "Ready").

Notification System:
Added a notification system to display messages (e.g., "Activities loaded", "Connection failed").
Notifications appear at the bottom-right corner and fade out after a few seconds.

You should take in consideration few things about Sugar/Sugarizer

• It's targeted for children between 6 and 12, some of them can't read (so we tend to avoid "text") and some of them have never used a computer before (so applying what you think as "usual" icon is not necessarily a good idea).
• It works both on computer and touch devices so concept of tooltip/hover effect and cursor are not always appropriate
• It was thought for children that could have visual disability so a colorful screen is not always the best thing to do
• We expect that children could focus on activities so we tend to avoid multiple windows

I don't think your suggestions are interesting in our context.
