As many times, this box causes unnecessary obstacles in using the interface to manage/ resolve duplicates, especially for new learners. It may be solved by making mobile like caller's image in skype.

Ability to highlight and add notes to the uploaded PDF attatched

Include a "notes" feature so that notes can be added to individual articles

An option to manually highlight in abstracts

Differentiate selection based on abstract and title AND selection based on full text.

Calculate Kappa statistics for Concordance between two reviewers

When uploading PubMed xml data, only the TI field is added to Rayyan. If articles not in English only populate the TT (tranliterated title) field, then no title is included in Rayyan. Using the TT field if the TI field is empty or "Not Available" would aid in screening.

Be able to edit/add abstracts to records if they didn't import.

I can export files in RefMan format (I don't think RefMan exists anymore as of last year), but not Mendeley. Could you add that at some point?

keep all original bibliographic data!

When uploading references and subsequently downloading these references some information is lost. eg the following fields are empty after downloading from rayyan. DOI, name of database, database provider, keywords, date field. These field are at times necessary for further processing so would it be possible to leave the original reference intact when exporting back to reference software.

One essential featire that is need for this app is to have the opportunity to remember our screening position (that is which article/record number) We let reviewed and start us from there. Every time I open the app, it takes me to the beginning of the articles to be sxreenes is 1/xxx and I have to scroll to number 100,200, etc from there. That is so so so inefficient. Please improve the app to enable us continue fro. Where we left off. As is, it makes things very tedious.

Add ability to upload text file with record of replicable search strategy

Provide a "No label" filter option so that a reviewer can see the records that don't have any labels assigned to them.

It would be useful to be able to edit the description once a review has been created.

Ability to pre-define consistent inclusion/exclusion reasons for all reviewers in a project, to be set by review owner.

It would be useful to have a desktop version of Rayyan which allows offline work to be done but syncs with the web when online (like the mobile app) .

Allow to identify a reference as duplicate when not picked up by Rayyan

Create custom groups

Add capability to edit labels by batch (ie, modify label and have changes carry through all records with label).

PubMed records often include DOI field. Linking to the article via DOI resolver would speed up full text assessment where needed.

Search box is useful only for searching for a specific title but it doesn't work for searching by author or system ID. Expanding the searching capabilities of this feature will be beneficial for improving discovery within the system.
