What actions do all variables allow within a flow?

The ability to be renamed is a common feature for all variables within a flow. Renaming variables allows developers to maintain clarity and organization within their workflows. This can facilitate better understanding and management of the flow, particularly as it evolves or as more variables are added. By being able to rename a variable, developers can ensure that the variable names accurately reflect their purpose or the data they hold, which aids in both debugging and future maintenance.

While assignment of new values, tracking data changes, and being fixed in data type are attributes relevant to how variables can function, they do not apply universally to all variable operations. Renaming, on the other hand, is an action that can always be performed regardless of the variable's type or usage, making it a fundamental aspect of variable management in flows.
