Make this feature available to anonymous users savind data trough cache

Is it possible? Would maintainers of the module consider to include such a feature in the future?
I would like to enable the visitors of my site to collect list of the articles (nodes) they could read later at their convenient time without registering on the website. Or maybe there is already another module providing this feature to anonymous users. If there is, could anyone suggest a link, please, since I did not find one.
