Query warnings are all but illegible.

When a query run through the workbench produces a warning, the only way to view this is via the tool-tip pop-up for the warning icon.  The content of this pop-up is the raw JSON warning but this is presented unformatted (not "pretty") and in a variable-pitch font making it hard to read.

Ideally warnings should be accessible elsewhere (like in a tab along-side results) or at least be presented well formatted and in a fixed-pitch font (so the formatting makes sense) in the pop-up.
