MX 2.0 migration issue tracker

## Issues

- [ ] API only allows to filter by 1 title pack
This is only an issue with TMAll, since we used to include it + the 4 base title packs

- [ ] Author filter doesn't work with multiple authors
The plugin used to allow you to search by multiple authors, which doesn't work in 2.0

Those are the ones I found while migrating the plugin. I will add more when anyone encounters more
