HTML View (Plasma 6 Widget)

A powerful and versatile HTML/Web view widget for KDE Plasma 6, designed for dashboards, monitoring tools, and custom desktop content.

Key Differentiator: Support for Local Files with drag-and-drop loading, making it perfect for custom local dashboards or HTML widgets.

Features

• Local & Remote: Seamlessly switch between local HTML files and remote URLs.
• Drag & Drop: Drag an HTML file or a remote URL onto the widget to load it instantly.
• Suspension Mode: "Pause" the widget (via toolbar) to stop rendering and disable JavaScript, saving CPU/RAM when not in use (e.g., for 3D printer dashboards like Mainsail).
• Transparency:
  • Supports transparent backgrounds (select "Transparent" in Appearance).
  • Force Transparency: Optional script to remove backgrounds from stubborn opaque websites/SPAs.
• Security & Isolation:
  • Runs in an isolated WebEngine profile (cookies/cache don't leak to other widgets).
  • Configurable security policies (Mixed Content, Remote Access for local files).
  • Option to ignore certificate errors (e.g., self-signed).
• Usability:
  • Auto-hiding navigation toolbar (Back/Forward/Reload/Suspend).
  • Toggleable scrollbars.
  • Zoom/Scale control.
  • CTRL-click on a link opens the link target in the default browser.

Configuration Guide

General

• Refresh: Set optional auto-refresh interval.
• Security:
  • Mixed Content: Allow HTTP content on HTTPS pages.
  • Access Control: Allow local files to fetch remote resources (CORS).
  • Certificates: Ignore SSL errors (useful for self-hosted local tools).

Appearance

• Background: Choose "Transparent" (No Background) for a floating widget look.
• Force Transparency: Enable this if your web page has a white background you can't remove. It attempts to strip the background via JS.
