very nifty little add-on to speed up my lit-reviews. author has been very responsive to improve usability! check the options tab or assign a keyboard shortcut. robot checks by sci-hub are now caught but not always, at least in my case, and you might get a false "pdf not found in sci-hub". some mirrors of sci-hub seem to do less robot checks than others, so play with that.

Bless you

Insane how science keeps going only thanks to things like this

It's a great app, really helped me with literature review. Thank you to developers, for making my thesis writing less miserable!

Found this little gem on Reddit. It works swell, even with Amazon books! It's insanely good. A "must have" for any student or graduate student doing research.
