It just occurred to me that, although we can use the ?Cat= feature to bring up just the boards we want, because they are called by number it is immediately obvious, when we have some hidden categories, that they must exist because there are numbers missing from the sequence. It is also not easy to figure out what the number is of the Cat we want. Perhaps we should use a short (3-letter for brevity) name instead? Easier to identify and doesn't show the gaps.
