Hi,
I have a first rough implementation of conditional objects in templates.
An object in a template file can have an extra attribute called
'conditional', which holds a condition like 'varname==value'. '==' can
be '!=', or '<=' or any other expression. 'varname' is any $CONFIG variable.
In the example the messagelist is only shown if the mailbox-name is 'INBOX'.
Am I going in the right direction?
Robin
