Hi, Jun and Sebastian,

This is not trivial, but it is already being done with some tools using the
method described at
https://wiki.galaxyproject.org/Admin/Tools/Multiple%20Output%20Files#Single_history_output_Html_file_with_links_to_any_number_of_output_files_and_images
if
that can solve your problem. The Galaxy Html composite datatype can be used
to expose arbitrary outputs without creating a separate history item for
each one if that's what you want. The tool executable or the wrapper must
write valid and complete Html content to the path Galaxy provides as the
Html file for the tool and the sanitize_all_html switch must be turned off
in universe_wsgi.ini (which is a potential security problem for public
sites!) for the page to be pretty, but since the script itself is
generating all the output it is possible to write code to create a nicely
laid out page of links and images for the user. Composite datatypes (like
Html) are documented in the wiki and contributions to the wiki are always
welcomed - but at present, it's an advanced and not well documented
possibility.

If there really is demand for this functionality to be exposed, I have been
thinking about an autoHtml datatype that would do what the tool factory
does - look inside the job working directory at the end of the job and
arrange every file it finds there into a simple Html page of links. If
https://trello.com/c/vNQLZnSk gets enough upvotes, we'll put it into the
development pipeline?
