Hello, I would like to submit my own URLs and contribute my own history, but I am forced to use ChromeOS and have no option to import chrome data.

1. This is the best option, please add a way to upload a text document or csv document, and it will automatically phrase the document and Grep the URL list and add it to the crawl, so that it can be added. This also allows you to have large scale URL imports added.
2. A more complicated and less versatile solution is developing a chrome extension for the WDP.
