For example, automatically generating missing citation keys based on AuthorYear, rename pdfs based on citation key, show citation key in the main window, and find duplicates (mentioned elsewhere).

I'm a blogger and online article publisher. I realize Mendeley is incorporating support for Zotero, although unfortunately Zotero doesn't appear to be doing the same for Mendeley. The Zotero developers aren't interested in a Chrome extension for Zotero anytime soon either. But I would really like a Zotero-like Mendeley extension for Chrome especially (now my primary browser), but also Firefox, for both creating bibliographic entries in Mendeley and also inserting them and citations into web forms like Google Docs and WordPress for posts and pages.

The Mac application Papers has many useful features for building and maintaining personal libraries of publications. Would be very helpful for users to have one combined library rather than a Papers library and a Mendeley library.

See: https://developers.google.com/drive/
Files can be stored on Mendeley's servers but listed and indexed in individuals' Google Drives (the new name for Google Docs). Thus people can keep all their cloud services in one searchable virtual place.

On Document Details tab, the default search engine to fetch detail information for a paper is Google Scholar. It would be nice to instead use Google Patents "www.google.com/patents"; or the uspto website "http://patft.uspto.gov/"; when 'Patent' is selected for document type and the patent number is entered manually.

It would be very useful if one would be able to see all of the annotations, notes and highlighted text in a list without having to open the PDF and go page by page. This way, one could highlight the most important parts of a document and see all of this text when clicking on the record. In the future this could be tied into citing specific sections of documents where Mendeley could automatically insert page number if a specific document section that was highlighted/annotated needs to be cited.

Could be usefull to navigate between your previous position within the PDF. It would be even more necessary if you make the hyperlinks within the PDF operational.

Add a logout function for Mendeley desktop, so that it can be used on shared computers, or persons managing multiple libraries can switch easily

it would be great if we can integrate a document that was using endnote for citation with mendeley

Nokia cells are great machine. It is a great improvement if it is possible to make a version for this OS.

It will be great to have the Mendeley application for the PocketBook e-reader. To synchronize the collection of articles along with all associates notes through the cable or online.
NB: PocketBook is the only one completely pdf-friendly e-book reader, especially 903 model which I use.
PS: GPL license for the Mendeley could resolve this problem also.

One for the author's abstract (if any), one for public notes by the collector about the article and one for the collector's private notes about the article (which might include candid or critical thoughts they would not want to share). Meanwhile by default the "notes" field should only contain the abstract. When I imported from my Endnote XML file it imported my (candid) "notes" field in preference to the abstract when both were available.

It would be very helpful if mendeley could support the option of:
1. non-Latin languages citation formats - when you don't use English articles the program still using terms like "In" or "eds" and I have to fix it.
2. Supporting Left to Right languages like Hebrew and Arabic.

The options are limited at the moment. While allowing to suppress the author in v1.6 went a little way to help, you should also be able to do the same with the year and leave only the authors name this time. The ability to hide parenthesis would help with writing, while still allowing you have enough control over the citation.

It would be great to automatically get cover images of books (by isbn) and display them with the books in result lists - kind of virtual bookshelf.

Mendeley should be able to export to the XML format of bibliography accepted by MS Office 2010!

in the iPad app at the moment you can either look at "Recently Added" and then browse the papers alphabetically or look at a collection. It would be great if we could sort on "Date added" and also filter using tags as I don't remember the title of each paper, but I do want to read the one I added this morning....

for example upload current favourite Mendeley articles to eReader
