When i reference a config Item(Report, Grid, etc) in a Item Ribbon tab config this reference points to a specific version of the config Item. This means that if i create a new version of the config Item i will have to reconfigure the Item Ribbon in question.

I think that a more common scenario would be that if I create a new  version of a config Item, i want the Ribbon to use that version just like it works for the "normal" ribbon or the dropdown menu.

<ItemRibbonTabConfig>
	<Contexts>
		<Context caption="Teknik Demo" color="Red"/>
		<Context caption="Roles" color="Blue"/>
	</Contexts>
	<ItemTabs>
		<ItemTab caption="Safety" context="Roles">
			<RibbonGroups>       
				<RibbonGroup caption="Safety">          
					<ItemView name="Report" configItem="x3400000000BC3653" visibility="Dynamic"/>                                                       
				</RibbonGroup>
			</RibbonGroups>
		</ItemTab>     
	</ItemTabs>
</ItemRibbonTabConfig>

From a single database perspective, the id (if using the same algorithm as for reports appearing in the "normal" ribbon,) is a much more stable approach since report names are changed from time to time. I do however agree that for people working with more than one server, this is potentially a recurring scenario.
