Omnivore is a relatively new read-it-later service; it still has very limited features, but it appears to be very promising.
I am testing it to save articles and web pages both that I intend to read later and that I read already and want to archive.
In the second case, I often find myself highlighting parts and annotating some comments on what I read.
It would be super awesome if highlife parts could automatically be synchronized as blockquotes in an Obsidian note, and my annotations for each highlight below each note.
Furthermore, the synchronization could take place the other way around, too: styling and links I create on Obsidian could be updated on the Omnivore annotation, using their API.
