It is constantly frustrating that every year Adobe fails to update InDesign with external Style functionality.

It should be easy to define a set of Paragraph Styles and apply that as "Global Style" which can then be used
across multiple InDesign files. Updating a "Global Style" would then apply those Style changes to all affected documents.

This should apply to all things that can have styles applied, Table, Object, Paragraph, Character, etc. Any of these different styles should be able to be saved to an External Global Style — that can be then saved externally locally — or saved to the Cloud and applied that way.

Currently this is not really possible and it's deeply annoying. I should be able to easily create a style that can be applied to any document I wish, and have any adjustments I make to that style automatically apply to all documents using it.

Obviously there could be a simple dialog box that prompts when opening a document using a global Style that has been updated. The user is then given a choice to update the document so that it is in-sync with the style updates, or create a new style from the previous state, or keep all the current settings and not update the documentand keep the older style settings without overriding them with the new updates from the external Style.

COME ON ADOBE. IT IS 2020.
GLOBAL STYLES. Without them updating documents in the same sort of style language is a massive pain, because any evolutions or changes to a style in one document immediately makes all other documents out of sync — this is a very common use-case problem deisgner run into, and the fix to it is very strightforward.
