While working in Service Studio using Dark Theme, selected elements such as Assigns, Decisions, Aggregates, Actions, Loops, and Connectors can be difficult to identify, especially when:

• Screen brightness is low.

• Working with large and complex logic flows.

• Presenting or sharing screens during meetings.

Currently, the visual difference between selected and non-selected elements is quite subtle, making it challenging to quickly locate the active element and follow the execution flow.

Suggestion:

Introduce a High-Contrast Selection Border for selected elements. When a node or connector is selected, display a thicker, high-contrast border (for example, bright cyan, yellow, or orange) around the element. This would make the selected element immediately stand out from the surrounding workflow, improving visibility, reducing eye strain, and enhancing productivity when working in dark environments or on large server actions.

This enhancement would significantly improve the overall usability and accessibility of Service Studio's Dark Theme experience.
