Wherein we celebrate the simplest of interfaces.
The Log Panel presents diagnostic information for your perusal.

console.log("My log info") to
display info here.Level Menu presents a menu of level filters. Selecting eg notice causes
all messages lower that this level to be hidden.
Filter Toggle toggles the filter input field to enter noise-reducing
search terms. Entering text into the input field filters out any messages
that don't include the text. If you are a regex guru, go crazy. When your
filter is invalid regex, we fall back to a simple string search. Clear
the input field to message-content filtering. Remember even when a
non-empty input filter isn't visible it will quietly do its work.
Copy Log copies the filtered text to your system clipboard. From there
the world is your oyster. This op is present in the panel's context menu.
Clear Log clears the contents of the log. Contents are erased without fear
or favor. This op is present in both the panel controls and context menu.
