.data is more suited for storing things like a file database (SQLite or NeDB): the characteristic of this folder is that it won't be "remixed" by people that are remixing your project.
On the other hand, you can place the build files wherever you prefer in your project, if they don't contain sensitive data.
Unfortunately, we don't yet support officially seeing changes that happen outside of the editor, but it's a work in progress. The closest thing you can try, but it's kind of cumbersome, is placing the results in a directory that the editor will open (the editor doesn't open files in directories that start with a dot).
To then see the results, you can force the refresh of the editor my editing a
.gitignore file (you can just add comments,
#, inside this file so they won't have any effect). The editor will refresh after 10 seconds and you will be able to see the auto-generated files.
We understand that this is far from optimal or pleasant, but we'll provide a better way soon
