-----------------------------------------------------------

I actually don't much like the collection drop down on the left. If anything 
goes it should be that. It's terribly hard to use if you have >10 collections 
or collection names longer than "foobar" Make one Time Routed Alias with daily 
collections for a month (which soon creates 30 collections named 
tweetsOrSomething_2019-06-XX) and then try to find your other collection 
"foobar" among the 30 wrapping entries in that drop down ...  yeah you have 
type ahead, but the drop down part becomes entirely useless. If you don't 
know/can't remember the collection name (or are exploring a new client's 
install on a testing machine?) the drop down is a pretty bad view of what 
exists. (and you would never even find the aliases without a lot of looking). 

One convenience for testing what things look like with lots of collections 
would be to create a TRA with a start date in the past and set maxFutureMs to 
something very high, and then send in one doc (via documents) with an id and 
the current date... it will then create a bunch of longish collection names for 
you. Note that I once did this with monthly collections since 1970 (a client 
was trying and luckily failing to do that, I did it just for fun locally to see 
if it could even work) and it crushed the system and died after the 500th 
collection and like 20 minutes so don't get too carried away :).

> After having recently toyed with Time Routed Alias in SolrCloud,
> we have noticed there is no way to query an alias from the admin UI,
> since the combo box only contains the current collection in the cluster.
> Solr Admin UI ought to have a way to query these aliases, for better 
> convenience.
