Hi, I have been developing a few tools where the number of output files cannot be determined before the tool is run and I have been following the protocol on the wiki which works well. I do have a couple of issues: 1. Naming files - The returned history items are all returned with the same label, is there anyway to edit this? Perhaps I missed something simple or do I need to add a post-processing step somehow? 2. When I have several additional outputs or large output files these take longer to find their way in to the history and are often missed by the first automatic refresh (force_history_refresh=true). If I wait a few seconds and refresh again the extra history items appear. Would it be possible to check that all outputs are loaded before refreshing or to wait say 5s after the tools has completed running before refreshing? Any help with this is appreciated.
