Maybe take a look at Shiori (https://aki-null.net/shiori/). It's more of a stand alone app rather than a Chrome Extension but the well crafted solution (afaik works with chrome and safari) combines pretty much all needed features. Basically use it on a daily basis for the saving process although I have to say that I prefer Alfred App scripts to access the bookmarks on my Mac.

I've been using Pinput for Pinboard and have been very happy with it:

I use the bookmarklet. No overhead, plain simple.
