I can confirm that the missing table numbering as described in #594 is fixed after installing from the feature branch (and updating rmdfiltr, dunno if this is important).

The problem with cross-referencing of appendices (e.g., "Appendix 1") persists. I will open a separate issue for this one.

Unfortunately, I cannot give any reasonable feedback at the lua level.

Awesome, thanks!
