Yes agree, it is much easier to modify the raw code this is an extreme way It is a simple example to understand how we can expand application without affecting the source code

Just example: i would like to add custom zone sizes in select box with sizes

Hello, How can i change existing form , for example zone-edit form, by custom plugin? zone-edit form don't call hooks "beforeContent" and "afterContent" where I could change it. I found "buildZoneForm" metod and we have there : if ($oComponent && method_exists($oComponent, 'processZoneForm')) { $oComponent->processZoneForm($aFields); } but how i can set my custom component to $oComponent, without changes in core, Any Idea? Thanks!
