After a few months of not working on Indieweb related software, today I have added bookmarking from Ekster Reader. I wanted this for a long time but never came around to implementing it.
Together with the bookmark feature, I also added syndication targets. This allows you to select one or more syndication targets from your micropub software and are sent when posting.
This is very useful for me, because I want to syndicate my bookmarks to Pinboard.
