I've been using Mendeley Desktop since a couple of years ago. Recently, they have released Mendeley Reference Manager. Both support cite as you write.The interface of Mendeley Reference Manager and integration with MS word seems better than the other release. However, as far as I understand, Mendeley Reference Manager does not support local storage, while Desktop does. I'm still using Mendeley Desktop because I'm used to read papers through it. Also, having tons of articles stored locally, it will require a subscription and I'm afraid a large library will worsen the performance of this new edition.
Based on your experience, have you noticed any improvement of your workflow by switching from Mendeley Desktop to Reference Manager? Is it worthwhile to shift from one to the other?
