* [CHD-3381] [Mail/Reply/Custom Fields] Custom fields and fieldsets can now be set again while replying to tickets.  Previously, this functionality set values for all custom fields regardless of whether or not they changed.  This caused problems because workers that were changing the custom fields on a ticket during the course of a long reply would have their changes overwritten when the reply was sent.  Now the worker sending a reply may choose which custom fields to set, and the values for everything else will remain unchanged.
[Code Cleanup/Dates] The smart date inputs will no longer auto-focus the first autocompleted result.
* [CHD-3383] [Mail/Reply/Usability] When replying to a ticket, the "Would you like to move this conversation?" question now shows the current group and bucket in the default answer.  For example: "No,  leave it in the inbox of Support".  Previously, workers had to open the picklist and scroll around to find where the conversation was currently located before they could decide if they wanted to move it -- this wasted the time spent moving a conversation only to find out that it's already at the destination.
