Markdown Viewer Locale

This module adds a small Markdown icon button to the control panel of every form view. Clicking it opens a popup window that lists available documentation, grouped by category, and filtered to the model currently open (for example, a partner form shows only documents registered for that model or for all models).

When a user picks a document, the module tries to load a language-specific version of the file based on the user's language (for example, a Bulgarian user gets the Bulgarian file if it exists). If that file is missing, it falls back to the default file. The Markdown text is converted to formatted HTML with syntax highlighting for code blocks.

Inside the document popup, a search box highlights matching paragraphs, list items and headings as the user types. A "Back to Index" button returns to the document list. If no documentation is registered for the current model, a warning message is shown instead.

The module does not create any database models or menus. It only extends the existing form view interface and relies on a central registry where documentation files are declared with a title, category, description and the list of models they apply to. One general "Welcome Guide" is registered by default for all models.
