Tab Save is a utility to save all files in open tabs within Google Chrome to disk.
All open tabs in the current window are saved to disk, but I might add the ability to change this behaviour on the options page, e.g. for all windows, in/active tabs etc..
Filename can also be specified as the page title by setting filename in the chrome.download API. Hooking this up to a Google Scholar API will allow this extension to automatically name PDF files - this code contains a working prototype but the finished product is still in the works.
This extension largely just uses the core download method. Feel free to fork and make more elaborate use of it.
The current build is available on the Chrome web store, and now features the ability to add a list manually rather than just from the tabs list.
