I've just tested the newly implemented "Full text article download" function, however for several articles it downloaded a version from ResearchGate but I want to have the one from Elsevier. Dependent who you are working for, you have special access privileges on certain publisher sites where you download papers.

It would be handy to specify (in the preferences) which publisher the download pdf function should prefer. Perhaps even define a priority list, e.g. Sciencedirect (Elsevier), Wiley, ResearchGate, google, etc..
