UpUp VS ShellNewHandler

• Easy to implement
  UpUp can be set up with just a few lines of JavaScript and requires minimal configuration, making it accessible for developers who want to add offline functionality quickly without deep knowledge of Service Workers.
• Lightweight library
  The library is small in file size, meaning it adds minimal overhead to page load times while providing offline fallback capabilities for websites.
• Simple offline fallback page
  UpUp allows you to specify a custom offline page that is displayed when users lose internet connectivity, improving user experience during network interruptions.
• Built on Service Worker technology
  It leverages modern Service Worker APIs to cache content and enable offline access, aligning with progressive web app (PWA) best practices.
• Free and open source
  UpUp is available as an open-source project, allowing developers to inspect, modify, and contribute to the codebase without licensing costs.

Possible disadvantages

• Limited maintenance
  The project has seen infrequent updates in recent years, which may raise concerns about compatibility with newer browser APIs or long-term support.
• Basic feature set
  Compared to more robust PWA tools like Workbox, UpUp offers a fairly minimal feature set, lacking advanced caching strategies, background sync, or push notification support.
• Browser compatibility constraints
  Since it relies on Service Workers, it does not work on older browsers that lack Service Worker support, limiting its use for sites needing broader legacy browser compatibility.
• Limited documentation depth
  While basic usage is documented, more advanced customization or troubleshooting scenarios are not well covered, which can make debugging harder for complex use cases.
• Not actively promoted as a modern standard
  With the rise of more comprehensive PWA frameworks and tools, UpUp is less commonly recommended today, which may result in a smaller community and fewer new resources or tutorials.

• I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?

  Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago

• This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?

  I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
