I just added a feature request but as in the past, I suspect I will never hear or see anything of it. Not even a mail saying that it was received copying me my request. Thats pretty bad service.
So for posterity, here was my request:
Add command line and config file properties to control:
+a message in the horizon view username password entry dialog (Some organizations have internal control policies that state that before even entering a username and password that you must see disclaimers so popping one up after you have entered your credentials isnt good enough.)
+customize the messages in the red banner during connection errors (they currently lack clarity especially for an end user)
Ability per pool to specify groups of users that are allowed multiple sessions\desktops (currently we must make multiple pools which is an administrative burden)
