Hello,
I'm trying to customise backend of Joomla to make it as simple as possible for my very, VERY er... unqualified users, meaning - I got rid of all elements that aren't 100% necessary and could make them go 'hm, what does it do? what if I?...'
Thanks to cpanel.php that you made possible to be overriden, I moved few icons to 'admin-only' view (including 'Categories'). I've tried to do the same with backend sidebar, but met a little of disconsistency here. While I can override cpanel, I actually can't override sidebar, as its content is defined in /administrator/com_jevents/helpers/jevents.php, which obviously can't be overriden.
Please, consider this feature in future releases of JEvents.
Cheers,
Olek
