just a small thing, but the "MadeBy" filter in the CA market is... difficult to use. if you have a short username or one that happens to be part of other words, it is often impossible to filter out only your own work.
for instance, if i search for CA made by king, i get multiple pieces i did not make because the other users also have "king" in their usernames.
allowing us to search by ID (or, probably even better, using a format like user #0000, like lookups show) would alleviate this issue and allow for a much more exact search.
it could be optional, allowing people to search just for a word, or use the full combination for exact results.
