Immediate access to previously accessed PDFs integrated into a Google Scholar search?
Google has brought a whole new experience how we tend to manage stuff. Searching is so fast and efficient, that in some use cases it has become obsolete to maintain a rigorously structured, personal library. The drawback, however, is that you have to complete the tedious task of retrieving the full text PDF again and again.

I am a scientist myself, and I am also one of the developers of Paperpile, where we exactly tried to make this use cases as simple as possible. Paperpile runs in the background and you do not have to leave Google Scholar or Pubmed to quickly get the full text PDF.

Next to each item in the Google Scholar search result you will find the little Paperpile toolbar. Just click on the Paperpile logo and it will find the full text PDF for you and will add it to the library. That's all done in background, and you do not have to open any user interface or go to another window.

Paperpile automatically screens all the items on the Google Scholar results page, and shows a link to the PDF for those that are in your library. Since Paperpile is totally web based, this will also work if you login on another machine.

I have also attached a screenshot to get an impression how it works. Articles that I already have in my library are marked by the green logo.
