One feature that would be really useful to us is the ability to save states of components easily. Here's our use case.
We have one page that has about 20 different filters on it (which all then modify the SQL query). If the user has a go to pre-set it's not a great experience for them to re-enter the filters every time so we created a "Save Filter" button that now has a LOT of logic to save to a DB, recall and reinstate when we want to do this. Ideally this can be simplified as I'm sure there are many components that would benefit from persisting in value through multiple sessions
