I am in a Systematic Review workshop, and we are looking at Rayyan along with some other tools. A concern from several participants is what would happen if QCRI stopped supporting Rayyan or if it was bought by Elsevier, etc.

Making Rayyan an open source prioject would help allay some of these concerns. The QCRI team could also benefit from community input.

Extraction tool

Just like "undecided", there should also be "unlabelled" category

Ability to rename, delete, and merge labels and exclusion reasons. Badly needed!

blinding of author/institution/journal

I think it would be very useful if the keywords were not capital sensitive. Thank you

A count of total number of cumulative conflicts (and between which reviewers) throughout the whole review process, even after the conflicts have been resolved.

Automatisch verspringen naar het volgende artikel als iemand heet geïn- of excludeerd.

Make it possible to add comments to the different References that you include or exclude.

Logical rules to deal with inclusion / exclusion:
ie: A and B say include but C says don't -
allow to make A a higher priority member so that A plus B or C would be included but
B and C without A would still be a conflict

make it easier to toggle between the refs you have screened and those you have yet to screen. It's very unstable as it is. You have to screen in small batches.

Using keywords or labels to exclude (rather than include) abstracts when filtering

Often I want to remove an exclusion or inclusion reason, or a label, but I'm unable to scroll down to the bottom of the list of reasons/labels. I see all the reasons/labels that I haven't assigned to a particular article, but ones I want to remove aren't accessible. This might occur more often when there are lots of reasons/labels - I don't remember.

Being able to use AND when two or more labels are selected. Eg a reference must have both selected labels to be displayed. Currently all references that have either of these labels are displayed.

Add an indicator next to folders on left (e.g. keywords, duplicates etc) which shows percentage of papers resolved in that folder. This may also be achieved with a colour coded strip indicating red for incomplete and green for complete. This would then enable a reviewer to move on to other folders without going back and forth into folders already resolved.

Add the ability to filter by year to your mobile app.

Be able to reject in two waves, so title screening and abstract screening can be done separately

Currently if I am in the "unresolved duplicates" category and delete duplicates, they get added to the "deleted" folder but they stay under the "unresolved" category unless I refresh it. Similarly, when I am in the "undecided" category and I include or exclude an article, it stays in the undecided category until I go into the category again. It would be good if these were automatically moved out of these lists after applying these actions, as it gets confusing & is annoying to have to manually refresh every single time.

be able to filter based on whether it was judged by only one individual or both.
