Hello. First of all, thank you for the excellent grocerycrud! He is a very simplified my life)
During development, I used callback_before_insert, callback_before_update and callback_before_delete. Because I use my own functions for these operations (due to storage in the nested sets), then it would be useful to simply return TRUE from callbacks. And in this case, grocerycrud acknowledges the operation cre/upd/del performed. I added it to the library grocerycrud, but can it be done in a simpler way? If this functionality is not provided yet, you may wish to add this?

callback_insert , callback_update, callback_delete = those callback's skip the operation of the CRUD and only use your callbacks and they are TRUE/FALSE drived.

Indeed. I apologize for the stupid question. The theme can be removed.
