Feature request: Accept a URL to an input file

[slowkow]

Suppose we have a URL like this:

https://www.jkanche.com/kana/?10xh5=https://example.com/myfile.h5

It would be great if we could click that link and have Kana automatically retrieve the file and load it into the app.

This feature facilitates sharing with colleagues.

This feature also unlocks the possibility to create a light-weight Chrome extension (similar to BioJupies) that adds a "Kana button" to the web page when the extension detects a filename like *.h5 on the page. In one click, the file can be automatically loaded in a new Kana page and ready for analysis.

This feature also enables accepting a URL for a file in the input form instead of choosing a local file on the user's disk:

thats a great idea. it is something we are currently working on for a different data backend system and can add this feature when its fully tested. Also the UI needs to support both file drag/drop & urls and may be a redesign so that its not clunky with a lot of UI elements.

Probably don't anticipate this on most public servers that host data although we might run into issues with CORS when datasets are hosted through S3 (if the bucket hosting the file doesn't have CORS enabled)
