Visualize annotation from JSON for further modification

[umayerr]

Hi @alvi-khan, I must admit this is a super annotation tool. Thank you for the efforts. However, I am wondering if there is a feature of uploading the JSON (previously exported) file for further correction in annotated data.
At the current state it allows text to annotate with an wonderful color coding. But if we need to make some correction in the annotation file which is typically in JSON format then it needs to be re-annotated from scratch. So, the tool might have an option of uploading the JSON which will render the same color coded visualization that it had while doing annotation. Then further correction (removing wrongly annotated tokens and adding new tokens in annotation) would be easier. Finally, the corrected file will also be downloaded in JSON format.
