Within Crystal Report there is a functionality which will automatically add a match title once a field was added in the detail section. This is interesting when we are developing list based reports (might also be useful in other situation). When those fields are align you can easily change the width of 1 field and it will automatically resize the linked title.
Such functionality however is not present within iReport. It might be interesting to add a similar functionality which add a Text field or a Static Label with as content "Name of the Field".
When introducing this it would be nice that you can define whether or not currently created report needs this behavior or not. Within Crystal we sometimes need to remove all titles when not needed. If it could be turned of when introducing then we have best of both world.
