Summary

The interface currently supports importing a term list from a TSV file. This option should be removed.

Steps to reproduce

• Create a corpus
• Click on the flower of the corpus's Terms subnode
• Click the "Upload" action

What happens

The file format dropdown features the "TSV" option alongside the "JSON" one. Importing a terms list from a TSV file might already be buggy, and it will become buggy anyway once nested subterms become possible.

What should happen

There should be no option in the dropdown list to import terms from a TSV file.

Note that the option to import a corpus from a TSV file is not in question here, only the option to import terms from a TSV file should be removed.
