Users seek global variables for dynamic text updates and prototyping, improving design testing with real-time data like 'current date.' https://mostlyboating.com/painting-a-fiberglass-canoe/

Sometimes I need to create a prototype for something like, say, a form. I'd love it if we could have (global) variables for text strings that can be managed somewhere AND could be updated through Interactions.

Example: When a button is pressed, there's some logic attached that says: update the 'user name' global variable from whatever it is to 'John Doe'. Now, throughout the entire prototype (in preview mode), wherever that global variable is used it says 'John Doe'.

Bonus:

Add dynamic options to global variables such as 'current date' or 'current time'. Useful for prototypes that need to feel as real as possible.

It would be amazing to just define some global variables and use them inside the shape properties such as border-radius

Yes, please! It would be easier to maintain a complex prototype if we had variables especially if you don't plan well your components you end up doing a lot of copy / paste to update the values.

Add support to the System Variables like time, date, battery level, internet connection level and language. This can be helpful for multilanguage prototypes or some mobile apps prototypes that interacts with these variables and show timestamps, deny access for some artboards because of the internet connection that is required to access some part of an app and a lot more things can be made with this feature.

In a form based prototype there is a field in which you can select a date. I want the default to be the date of today, and that this automatically updates accordingly. So if you open up the prototype the next day, this displays the current date, without having to open up the design file.

TL/DR: Adding a text variable: date.
