+[ HTML Editor Panel Update ]
+This update gives the panel a clearer direction:
+
+Provide a custom subset of html for the main documentation format inside Roject. It should be readable as normal html file on computers and
+can be part of a webpage directory, which can be defined in css/js/headers. This will be a later part when needed but should be 
+planned with. Since the js part can be critical, only special js will be used when displaying the pages in the editor, effectively stripping 
+away any code.
+
+[ Naming Changes ]
+- HTML Editor Panel should be renamed to PageEditorPanel. This change should be done for all involved code.
+- This editor is no longer responsible for html suffixes.
+- This editor is now responsible for page suffixes.
+
+[ Editing Changes ]
+The editor will use a template for the html document with a standardized layout:
+ 
+The <body> will have this:
+
+<page-header></page-header>
+
+<page-root>
+
+  <page-block>
+  
+    <page-area>
+
+    </page-area>
+
+  </page-block>
+
+</page-root>
+
+<page-footer></page-footer>
+
+
+Whenever a .page file is opened that does not follow this format, the editor needs to reject the editing and fallback to normal text editing.
+
+[ Blocks and Areas ]
+Blocks (<page-block>) are full width html element templates with a specific structural layout.
+They could be something like 3 rectangles arranged in two halfs, 2 rectangles vertically aligned for images 
+and one rectangle on the right for text. Blocks can replaced and areas inside can be changed, but the 
+structure of a block is not changable.
+
+Areas (<page-area>) are containers for text, images and other inline elements.
+The allow rich text editing, from asigning font style attributes (color, font-family, font-weight, italic etc)
+
+
+[ Headers and footers ]
+Headers <page-header> and Footers <page-footer> will be there, but no features will be added yet.
+
+
+
+[ UI ]
+The ui should have two icons on the left which switch between blocks and areas.
+Blocks will feature a horizontal scrollable list of elements (canvas/html previews), while areas have buttons
+for formating the selected text.

+[ Tab Container Update ]
+The menu item "Split" will be a menu instead of an option and allows now to split horizontally (the implementated function) and to split vertically. 
+
+So the new menu points would be 
+
+Split > 
+        ↔ Horizontally
+        ↕ Vertically 
+
+
+The vertical split was planned from the beginning but somehow never implemented properly
+
+[ Tab Container Closing ]
+Currently there's no way to close a split tab container. That's why it needs under "Split" the option "Close Container", which will be available unless the container is the last in either the left, center or right slot - so that there's always at least one container in each 
+of them.
+
+Additionally to the menu point, another interaction should be added: Middle mouse closing. When an editor tab is clicked with middle mouse 
+it should close.

+        Extend the Rojo Chat agent with a built-in tool set — file system read/write operations
+        the model can call during a conversation. Generic across any OpenAI-compatible provider
+        (Claude, Gemini, Mistral, local models).

+      <h2>What it is</h2>
+
+      <div class="card">
+        <p>
+          LLM tool use (also called function calling) lets a model request that the server
+          run a named function and return the result, then continue generating text using
+          that result as context. The model never executes code directly — it emits a
+          structured tool call, the server runs it, and the result is fed back as a message.
+        </p>
+        <p style="margin-top:0.75rem">
+          For Rojo Chat this unlocks agentic workflows: a user can ask the Rojo to
+          "create a new page at docs/intro and add a heading and some intro text" and the
+          model will call <code>create_directory</code>, then <code>write_text_content</code>,
+          then reply with a summary — all in a single conversation turn.
+        </p>
+        <p style="margin-top:0.75rem">
+          The tool format used is the OpenAI function-calling standard, which is supported
+          by all major providers at their OpenAI-compatible endpoints:
+          Claude (<code>api.anthropic.com/v1</code>),
+          Gemini (<code>generativelanguage.googleapis.com/v1beta/openai/</code>),
+          Mistral (<code>api.mistral.ai/v1</code>), and local models via Ollama or LM Studio.
+          No provider-specific branching is needed in the implementation.

+          <li>Create <code>source/server/rojos/tools/</code> directory</li>
+          <li>Write <code>RojoTool.ts</code> (abstract base + context interface)</li>

+          <li>Write <code>RojoToolRegistry.ts</code></li>
