# Code structure

The Bulma module should be removed.
The actual Bulma-related code should be in the package [purescript-bulma][psbulma], which currently lacks some features.
The general style of the website should be in a module.

Modules should have their own specific API.
When a module currently requires to send messages, the API should reflect semantics instead of providing the module a way to just carry raw messages.
For example, there are currently modules able to send messages (with a very simple `MessageToSend message` API), but instead of dealing with raw messages that need to be built inside the module, the API should be more semantic such as `ChangePassword new-password`.

Once modules will have specific APIs, the entire state of the application could be moved into a single module (or *component*) so every state modification can be handled in a single place.

Minor modifications:

- split `App.Zone` to improve compilation times
- explanations and static content in general should be written using some kind of templates, not directly in Halogen

# Features

About zone records:

- allow '@' in record names (replaced by the fqdn, the "root" domain, such as "example.netlib.re.")
- enable to change NS records, but after a accepting the consequences

About the admin interface:

- enable administrators to ask for users' info and show zones
- perform a few more administrative operations (*TBD*)

Slightly more complex features to implement:

- zone-wise indications to help people configure their zone for specific uses (web, mail)

# Tests

Check for common errors:

- nodes with both a CNAME and another RR
- verify that SPF mechanisms point to available records

More specialized tests or debug options:

- verify the length of received messages in `App.Message.IPC`
- MAYBE: run `named-checkzone` on the genetared zone and provide the result in case of an error

# Display

- say that there is no IPv6 on the server at the moment, so there is no point doing IPv6 address updates
- admin interface: basically just rewrite the whole thing, it's a mess

Details:

- *maybe* notifications should disappear after a few seconds
- hide logs by default?

# General note

The code should be reviewed and a decent documentation should be provided.

Right now, the code is still in a somewhat early stage and **multiple** refactoring should take place.
For example, modules have a very generic API; they can provide or receive messages from (respectively *to*) authd or dnsmanagerd.
Instead, modules should have a more specific API and not deal with message encoding at all.
Furthermore, *maybe* the state of the entire application should be stored in a single module, with a single function handling all state modifications when a message is received, enabling a simpler data management.

# TODO in authd and dnsmanagerd

- enable users to change their NS
- MIGRATION-related: remove migrated accounts with no connection in over 6 months
