Here's an open source project of mine that is reaching maturity. Beacon is a Xojo-built tool for server admins of Ark: Survival Evolved. For those that don't admin a server, doing this without a tool or "by hand" is a maddening exercise. The definitions are a literal wall of text kilobytes long with no whitespace. So I created Beacon to not only make the process easier, but downright easy.
For Xojo developers, maybe there is some nugget of helpful code in there waiting to be discovered. The project contains everything related to the project, including artwork, icons, installer scripts, website code, and database schema.
