Can I turn off all the hints?
In your test directory, you can create a config.nims and put this in there for all the hints that you want to hide:
hint("Processing", false) # Do not print the "Hint: .. [Processing]" messages when compiling
https://nim-lang.github.io/Nim/unittest.html#JUnitOutputFormatter
Then use a tool to view the junit in all kinds of crazy ways, its like a standard-ish thing, you will find all kinds of tool to process and visualize these.
