1.3 Entry Operation Bar

Temporarily Save: Save the current annotated content. Exiting the current annotation interface or closing the browser after temporary saving will not affect the saved data.
Abandon: Give up on the current entry, which will automatically be categorized under "Abandoned" entries. Abandoned entries will not be counted in statistics.
Skip: Skip the current entry, which will automatically be categorized under "Skipped" entries.
Submit: Complete the annotation for the entry and submit it.

2. Right-Side Tool List

2.1 Task Entries

The task entry list will display all the annotation/review entries currently claimed by the user, along with their respective annotation/review status.

2.2 Pre-Check Warnings

Note that pre-check warnings are not provided in real-time. Pre-checks are conducted only during the temporary save or submission process. Users can also manually refresh the pre-check by clicking the button icon in the pre-check list.

Pre-Check settings are configured within the task settings. If the annotation results trigger a pre-check warning, it will be indicated here, and the operation to submit the data will be intercepted. For details on how to set up pre-check warnings, refer to the tool settings under pre-check settings in the task settings.
