General new features fo the letters:

• Define one or more letters, containing only specific snippet categories
• A new layout with the possibility to move around sections and add them in a flexible order

New features for snippets:

• Make snippets more flexible by including new placeholders that can be filled up by the users with something like a "wizzard" when being added to the letter.

Add the following features to the SOPs:

• Add tags to the SOP for better categorization
• Add some filters and a small search field to the index

Users need some kind of a "user control panel" where they can setup their profile, and change site specific settings.

• Create a small profile, including a picture.
• Re-send the activation link
• Change account details like the password or the email address
• Delete the account

Currently the layout doesn't really use flex and it looks pretty bad on small screens.

• Add breakpoints to make the layout flexible
• Make cards more flexible and without predefined size (what about preview images?)
• Move the <main> tag to the base.html.twig file

Update:

• Make the navigational tabs responsive in some kind of way...

Add the following features to contacts to make them more useful:

• Categories or tags that can be defined by the user
• Filters and a small search on the index page

When trying to access notes it just crashes with:

An exception occurred while executing 'SELECT n0_.id AS id_0, n0_.name AS name_1, n0_.category AS category_2, n0_.text AS text_3, n0_.created_at AS created_at_4, n0_.updated_at AS updated_at_5 FROM note n0_ WHERE n0_.category <> ? GROUP BY n0_.category ORDER BY n0_.name ASC' with params ["onboarding"]:

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'symfony.n0_.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

There needs to be a specific role that can edit the contents on the site, while not being able to access the backend. All other "normal" users should not be able to create or edit content.

It would be very useful to have some kind of notification that would alert users of new content or important changes.

There absolutely needs to be some kind of functional testing for the following features

• User registration, login and account activation
• Availability of important sites (like the homepage)
• CRUD actions of Infos
• CRUD actions of SOPs
• CRUD actions of Notes
• CRUD actions of Contacts
• CRUD actions of Letters
• CRUD actions of Snippets
