 A list of ideas and TODO. Don't hesitate to give feedback on the ones you really want or to propose your owns.
 
+0. Add book
 60. Unittest
 80. Search engine
 85. Anti-duplicate ?
 90. Look for published version in arXiv
 95. No DOI for HAL => metadata with SOAP API… don't want to handle it for now :/
 200. Webserver interface ? GUI ? (not likely for now…)
-300. Tree à la docear ?
 
 ## Thanks
