I find the current icon for the integrated Internet search in Lumo difficult to distinguish, especially with dark themes or low screen brightness. I suggest introducing a clearer, higher-contrast icon that automatically adapts to the selected theme (light/dark).

Possible implementation:
A minimalist magnifying glass icon with a subtle frame that is highlighted in color when search is activated.

Optional: A short tooltip display (“Start/stop search”) when pressed and held to support new users.

A clear icon makes it easier to find and activate the search function, which increases the overall usability of Lumo.
