Nice idea

[masteranza]

I guess, that it would be nice to have something like a stack of recently opened papers and better or better - a graph of recently opened papers with the ones cited by each other connected.
Currently, I'm using MarginNote for this.

However your current routine could be made easier by simply "touching" the file and sorting by "Date Modified".
You can update a paper your reading by adding, say a simple tag or modify it's Extra field.

I don't need citing graph. The extra field needs edit each jump, which is of high frequency for me. Thus one edit and remember the content of edit for each jump is not accessible for me. Better than that, one shortcut key each jump is easier. absolutely, this methods is better than no tool for history but not the perfect. I want to add a 'forward/backward' button on the GUI of zotero. Just like web browser. That will be the final solution. If anybody has any suggestions about how to make a plugin for zotero and can use it by zotero's GUI, I'll be very appreciated!
