The Search option is a very convenient filter.
If selection is used, it is very useful to apply common actions to said records. But you have to do it one by one.
It would be very useful if in the record selection, in the header, there was a select All box.
This option, combined with a previous Filter, would facilitate the execution of actions for a group with certain characteristics.
In turn, that All button allows you to mark/unmark all.
