Hi @AllanOXDi - overall this is a solid start. Adding in the validation based on Richard's recommendation is great. I know we may still change some of the wording for the strings, but making sure that they are all translated strings, and making sure that all of the functions are returning strings properly, is important.

I know there are quite a few places where this draggable with up and down is used, but could you please run your local dev server, with the console open, and go to view each changed file, and resolve any console errors? I've added one example inline of a place where I can tell that there will be an issue, but I'd like you to go through each file, look at the console, and fix any problems. It shouldn't take long, but it's blocking. Thank you!

Blocking:

• Capitalize the message strings

Non-blocking:

• I am conflicted about passing a Function that wraps a string. I love the idea of having a validation for passing along translated strings, but it is an unfamiliar approach.
• I wonder if we should export your isWrappedString validator from the kolibri.utils.i18n library so that we could start using it elsewhere.
• Namely this would be neat to somehow use with KDS as we pass many strings to those components.

Overall though this looks great - I think fixing Marcella's change request and capitalization should make this ready to go.
