In some cases user might now want to fetch results all the time, as their data might not be be as dynamic. This would speed-up listing and save bandwidth.
This will be implemented after: https://s3drive.canny.io/feature-requests/p/cross-client-online-sync which will be required to maintain consistent state across multiple clients.
UPDATE:
Since 1.5.3 and client-side ordering, we've implemented so called "cached mode" which allows to load file results once and browse results without connection to S3.
