Use case or problem
In terms of Security, Obsidian is a Electron App, and so far as my knowledge goes Electron isn’t strictly designed for web security in the manner a web browser is designed. (Correct me if I’m wrong.)
Currently, with the release of version 1.1, Obsidian’s new Canvas plugin allows for adding in webpages.
Proposed solution
Add a settings area for the Canvas Plugin, with a toggle that disables the adding web-pages feature.
Current workaround (optional)
I simply don’t use the feature…but the option is still there, and I personally don’t like having features be there that I don’t use.
I also from time to time use Obsidian offline on-the-go so I don’t even want to add web-enabled features that would “break” with no internet access.
Related feature requests (optional)
In the Future, possibly even add a feature to disable loading in web-content period–if the toggle is off.
