OmSave is a small, yet very useful Safari extension for OmniFocus which adds a simple toolbar button allowing you to quickly save relevant page information into your OmniFocus 3, where you can review it later.
OmSave will try to fetch the page metadata, like page description and main image, and store it in the note attached to the OmniFocus entry, alongside the link. You can fully customize the template that OmSave is going to use to create the entry, including setting default tags and project.
If for some reason we can't fetch an image from the page or the page didn't have any, OmSave can store a screenshot of that page instead, for your reference.
If you are OmSave user and you've got any questions or want to report an issue, don't hesitate to contact me.
