[Dolibarr-dev] Module Adhérents: how to custom ize?

[Tux]

Hi,

I would like to customize the display of the adhérents module :
1. the list of members : currently a table of 25 per page, I would
like to choose the number (50 or 100).
2. in the card page, some fields are of no use for us, I would like to
hide them.

Should I modify directly the PHP code? Or is there a better way, such
as a template to edit?
I am reluctant to modify the PHP code because of the work involved
when upgrading to a new version of Dolibarr.

I am currently using the version 3.0.0, almost only for this Adhérents module.

I read the 2 documentation page of this module (user and dev), without
finding this information.

I have other suggestions for this module, such as:
1. when adding an attribut, could we specify if it is optional or mandatory?
2. could we "remove" already existing attributes (the default ones). I
put remove between quotes, because it would just need to hide them.

Thanks
Yann
PS : I saw messages both in French and English on this list, which
langage is prefered?
