Version 2.3.0 — Major update

Graph improvements
- Nodes no longer overlap or hide behind the central focus node — the layout engine now treats every node as a physical circle that nothing else may overlap, including the focus node itself
- Zoom now follows the cursor position instead of yanking the graph toward the corner
- Individual nodes are draggable — move any node manually to resolve any remaining layout issues
- "Re-layout" button re-runs the auto-layout from scratch on demand
- Duplicate event listeners that accumulated over multiple inspections are now properly cleaned up

Notebook page inspection
- Hovering a notebook tab now shows it as a first-class element in the inspector: page name, label, position among siblings, count of contained fields and buttons, and the full arch XML node
- Notebook pages are now valid Inherit View targets — two new intents: "Add content inside this page" and "Add new sibling page after"

Python inheritance stub generator
- New Python stub button in the Info tab generates ready-to-paste Python boilerplate for 6 inheritance patterns:
- Extend model (_inherit)
- Override compute method — pre-filled with the field's actual @api.depends list
- Add @onchange for the inspected field
- Extend a selection field (correct selection_add + ondelete pattern)
- Override a button method (with super() call)
- New model from scratch
- Each stub can be copied or downloaded as a .py file

RPC console upgrades
- Method field is now a dropdown of 14 common ORM methods (search_read, search, read, write, create, unlink, search_count, name_search, fields_get, read_group, copy, action_confirm, action_cancel, action_draft) with inline kwargs hints for each
- New visual domain builder: load the model's real fields, pick a field, pick an operator, enter a value, press AND or OR — assembles valid domain JSON automatically without hand-typing bracket syntax
