I find that switching conversations is difficult when trying to select private conversations by the user's name. The difficulty is in the channel search which limits search to the text of the user's username. EX:
I want to look up "John Doe" (first, last names) whose username is "jdoe"
* Cmd+K to open switch channel search
* Enter "John", "Doe" or even "doe" produces no results
What I would like to see is
* all name fields/columns should be included in the search ("John")
* mid-string matching should also be allowed ("doe")
A looser matching paradigm would be more viable in channel searching b/c the search pool tends to be far smaller than that of the convo history.
