Doh, you're right - i missed SOLR-3677 :/ ignore my one, it does more or less 
exactly the same then yours.

What i don't know .. is difference between having something "global" (i.e. 
{{/solr/zookeeper}}) instead of relying on some specific core (i.e. 
{{/solr/collection1/logs}}) a difficult change? or is it only kind of "mapping" 
/ changing a listener or whatever?

Because, if we have all the global ui-options really global (available if we 
have no cores available) it should be a small(er) chance to type of initial 
state for the ui -- in that case we "only" have to avoid the step where the ui 
generates the list containing all loaded cores?

> Spun off from SOLR-3591...
> * having no SolrCores is a valid situation
> * independent of what may happen in SOLR-3591, the web UI should cleanly deal 
> with there being no SolrCores, and just hide/grey out any tabs that can't be 
> supported w/o at least one core
> * even if there are no SolrCores the core admin features (ie: creating a new 
> core) should be accessible in the UI
