Applications
The yavc.app-style title opens the same catalog in a desktop workspace or a single-application view. Try the editor, file browser, diagram tool and colour picker.
One catalog, three kinds of host
These working demos explore finding applications, browsing content and opening desktop tools through the host title. They use PUDL's menu bar, applet, Start, splitter and window controls.
PUDL 0.99.0 supplies the shared launcher controller and direct title-menu integration. The host adapter supplies catalog content, routing and saved preferences.
Content
A Bytecode.News-inspired browser puts a concise welcome page and featured links on the desktop background. Open articles over it, browse the resizable catalog, and use View to switch between Overview and List.
Desktop tools
An illustrative Dinah/GK Companion catalog replaces a separate Tools menu. Try working notes, a checklist, calculator, notifications, diagnostics and an expense worksheet.
Other launcher positions
The main studies place the launcher on the site menu's title. Compare the same application catalog with a separate top-bar button or a lower-left taskbar button. The placement stays selected when switching between the three studies.
What you can try
The host title toggles its catalog open and closed. Type to search, select a category and use the divider with a pointer or keyboard. Press the pin glyph to keep the catalog open as a pane, resize it, collapse it, and reveal it again. Unpinning immediately restores the popup; choosing a destination or clicking outside first makes unpinning close it. The Size button opens PUDL's popover with labelled dimension fields and a reset action. The popup also has a native resize grip.
Open several destinations and use their real PUDL window controls and taskbar. Copy the address to share the selected catalog state and open windows. Back and Forward restore navigation. Preferences and working drafts remain in this browser. Reset demo preferences restores the initial presentation and geometry without clearing working drafts or checklist entries.
For implementers
The catalogs and tools are illustrative. They are not connected to production accounts, article services, app registrations or native desktop bridges. Single-application mode uses a query parameter to demonstrate host policy; production hosts supply their own subdomain URLs and unsaved-work rules.
PUDL owns the menu bars and their hamburger controls, active application menus, catalog filtering, category interaction, keyboard navigation, splitters and windows. The shared launcher controller owns popup/sidebar switching, pin intent, placement, size and focus. The sample host adapter owns URLs, local preferences and destination actions. The same catalog node is retained while changing presentation.
