I've enabled VisualEditor as an option on the wiki, coexisting with the old source editor. This should make it easier to create freeform tables when necessary. It's still highly recommended to use the source editor to work with templates, as source editing likely remains significantly more efficient than visual editing of templates if you know what you're doing.
VisualEditor is not yet enabled for comments, though this is planned, pending the resolution of a display bug.
I hope this change is useful for editors. Please leave a message on my talk page or ping me on Discord if you run into any issues with VisualEditor. I don't anticipate this causing any breakages of existing source editor functionality.
