Feature: add a LocalStorage personal preferences

[tomsihap]

When I connect to the website, User can be able to save preferences (filters among other future things). To keep the app being a front-end webapp only and then to avoid managing user accounts, there could be a LocalStorage/cookies system to manage preferences as they are not critical data to keep.

Thank you for your feature request.

I'm glad to say that a user is already able to save preferences:

• config settings (only language for now)
• filters
• stars

Feel free to reopen the issue if needed
