I have a printout copy of many of my PDF files. Each printout is labeled with a unique number on the top right corner and stored in a ordered way.
Whenever I look for a paper:
1. I open my digital library organizer
2. I search the paper and find what is the number associated to it
3. Go to my paper library and pick paper number N.

I wish this could be done with Mendeley (sounds pretty easy to implement)

Many users may benefit from the ability to manage separate and distinct bibliographies in single document file. For example, if a file is a book/dissertation/etc with multiple chapters and the author wants to gather references after each chapter.

At the moment, there is no search functionality in My Library on Mendeley Web. It should support full-text search like in Mendeley Desktop.

the web version of the library always sorts the publications alphabetically in the title, it would be nice to be able to change that option, and be able to sort publications by date, date added, authors, journal, most frequently read (by yourself and others), most citations, etc...

It would be convenient to have a tool that copies an area of the pdf that you select and send it to clipboard as an image.

This would be useful when preparing presentation slides and you want to cite figures from other publications.

If you could come up with a way to sort search results according to year, publication etc

I would like to be able to delete (or rename) tags from the tag list. In my case I discovered I had two tags the really meant the same thing, and had to delete the extra tag from each document where it was applied instead of just from the tag list itself.

I find references while reading a document and want to be able to view them without scrolling back and forth from the content to endnotes.

When ever I start Mendeley it automatically start Desktop-Web Synchronization, there is no option to stop it. I want to Synchronization when I want, when I have high speed net at office place, not at home where speed is very low.

Please could you have a menu item which lists the most recently looked-at papers (e.g. the last 5 pdfs I opened)

... without duplication and floating characters after the year

It would be great if I was able to cite my references not only in Word, but also in Powerpoint (when I prepare presenations), and in Wordpress (for blogposts) and in e-mails

add dictionary widget so that readers can look-up words while they are reading.

I'd like to search for citations I haven't tagged yet. Especially to monitor automatic updates from watched folders.

For Windows: Would it be possible to have the option to keep Mendeley running in the background and when minimized, put into the notification area (bottom right hand corner)?

Some times you want to search for a reference you know is in one of your papers, although you can't remember in which paper. Instead of manually going through all the papers and looking at the reference list of each, it would be great if Mendeley could search all papers in you library for the reference you are looking for.

After importing a few papers with Windows 7 (x64) the "Search by Title" feature now quietly fails for me as well. I suspect this has something to do with Google Scholar blocking automatic queries to the service, since I now must enter a Captcha while visiting that site.

In my statistics tab, or a new tab for discovery, I'd love to be able to browse my own feeds, and have Mendeley generate some that may be of interest to me. For example, Mendeley could provide TOC of my top journals (working with ticTOCs?), and I'd also want the ability to add feeds of subject or citation alerts, etc.
