The support team is extremely responsive
Currently, SnailSVN only supports a relatively older version of subversion working directory (i.e., svn: E155021 error) but they offered me a quick solution right away. Even though they are planning to publish an updated version very soon. Kudos! The only issue is that it is a little bit overpriced :/
