Current Context In the current version of Service Studio, all Local Variables share the same icon (a yellow square), regardless of their data type. The only visual indicator that a variable is a List is the small expansion arrow on the left or the naming convention chosen by the developer. This uniformity makes it difficult to instantly distinguish between a single record/primitive type and a collection of data. The Proposal I propose the introduction of a specific icon or visual badge for List-type variables. Instead of the standard square, a "stack" or "layers" icon should be used. This would allow developers to immediately identify that they are dealing with a collection, rather than a simple Text, Integer, Boolean, or Single Structure variable. Why is this important? Reduced Cognitive Load: Developers would no longer need to hover over or click a variable to confirm if it is a single record or a list. Identification becomes instantaneous. Error Prevention: It makes data mapping to widgets (such as Tables or Lists) and the use of "For Each" loops much more intuitive, preventing type mismatch confusion. Improved Code Legibility: Complex actions with numerous variables become significantly easier to scan visually, enhancing development speed and overall Developer Experience (DX). Suggested Visual Changes Simple Variables: Maintain the standard yellow square icon. List Variables: Use a "List" symbol (e.g., three stacked lines ≡) or add a small "stack/layers" badge overlaid on the existing icon.
