Great product! Does it handle special metadata like https://mymind.com/ does, eg. showing prices directly in the UI if the saved link is a product in a shop? If not, things like that would be a great addition!
Site note: When a website advertising a product does a bad job at optimising the loading of the page, that's usually a red flag for me; yes that website has noticeable jitter when scrolling up and down even though it _only_ load around ~70Mb worth of assets initially.
