The Obsidian web clipper and web page preview from links are great functions for gathering material and doing research. However, it isn’t unusual at all for web pages to change or completely disappear over time. The contents link you might have collected point to can be gone the next time you want to refer to it.
The Webrecorder project has developed an open source browser plugin and standalone electron application that can provide small-scale (like single web page) high quality web archives that also takes in interactivity and embedded media such as YouTube videos. It is super easy to use.
This would be terrific to be integrated with Obsidian.
