 ## PROPOSALS
 
+### December-12-2025 Update
+
+Yes, it has been this long since I have been able to even look at this project again. I have thought about it a lot. Here are my latest thoughts, after moar knowledge gained.
+
+Let's start with the sigil and go from there.
+
+Elixir supports custom sigils. So we can define a sigil `~C` for ChEEx templates. (NOTE: I am unsure of the community patterns on custom sigils now that they can be multiple characters since Elixir 1.15, so this may change to something like `~CHAT`)
+
+```elixir
+~C"""
+<%= slack do %>
+  <.header text=":jigsaw: Discuss something" />
+  <.divider />
+  <.actions>
+    <.button text=":dart: Assign task" action={Actions.Tasks.new_modal} />
+    <.button text=":bar_chart: Survey team" action={Actions.Polls.new_modal} />
+  </.actions>
+<% end %>
+"""
+```
+
+This would be handled by a custom macro `sigil_C` that would use `EEx` to compile the string.
+
+The above can be placed within the block kit of a Slack message payload or a Slack view payload. For example, it can be placed in a view and published to app home.
+This can be handled a la Heex's layouts and slots.
+
+```elixir
+~C"""
+<.slack.view>
+  {@inner_content}
+</.slack.view>
+"""
+```
+
+### Phoenix implementation notes
+
+`Phoenix.Controller.render/3` takes in  a `conn` (`context`), a `template` (e.g. `:show`) (name of "action"), and `assigns` which is data that gets interlaced with the template.
+
+Similar
+
+view -> instead of determining "format", determines "platform"
+template -> instead of "show.html.eex", it is ":meeting_reminder"
+- based on the `platform`, it first looks for `templates/setup/meeting_reminder.slack.cheex`
+- else, it looks for `templates/setup/meeting_reminder.cheex`
+- route = `meetings#create_reminder`, params: `time: 5pm`
+- controller = `MeetingsController#create_reminder`
+  - `send_message(context, :meeting_reminder, users: [], ...)`
+- view gets created
+  - `views/meetings/create_reminder/slack_view`
+  - `views/meetings/create_reminder_view`
+  - `views/meetings_view`
+- view renders each template based on platform and action, and then controller
+- creates a view (if one is not created), (`View::MeetingReminder`) that takes care of the whole template (instead of phoenix has one view per controller with functions being the actions), I think this needs a set of template-only functions and controller-grouped functions....

 ### Support for seperate platforms
 
 I am unsure if it is possible to define one language dsl for all but I do know that exceptions will have to be made. I am think at the very best, you could have a "ChEEx DSL" and then have exceptions for each platform, similar to something like React Native. I think it would be wise to see how it looks for various platforms and then see if there are enough commonalities to create a common engine.
