 # Code structure
 
-- split `App.Zone` to improve compilation times
+The Bulma module should be removed.
-- modules should have specific API
+The actual Bulma-related code should be in the package [purescript-bulma][psbulma], which currently lacks some features.
-- *maybe* have a module with the entire state and a single function handling all state modifications on received message

-Also, the Bulma module should be removed.
-The actual Bulma-related code should be in a package (such as https://github.com/KaneRoot/purescript-bulma, 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
 
-- display a message when the email isn't provided (happens when the account was migrated from dnsmanager v1)
+About zone records:
-- zone-wise indications to help people configure their zone for specific uses (web, mail)

-- explanations and static content in general should be written using some kind of templates, not directly in Halogen
-- admin interface: enable administrators to ask for users' info and show zones
-- admin interface: perform a few more administrative operations (*TBD*)
 - allow '*' in record names
 - 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
