[galaxy-dev] download URLs limited to twelve?

One of our users is trying to download thousands of files by pasting their URLs in 'URL/Text' box of the upload tool. It seems like Galaxy selects only first 12 URLs and ignores rest of them. The issue can be reproduced on the main public Galaxy<https://main.g2.bx.psu.edu/> instance as well. I was wondering how can we remove this limit so that users can queue up thousands of download jobs in one click. Any help? -- Thanks, Shantanu
