The immediate high priority issue of losing line breaks has been addressed for our next release, which should be Jan 6th. There's still some funkiness/annoyance with the editor and spaces, but that might have to wait til the spring. It's using some old Microsoft Internet Explorer technology - we need to migrate the whole thing to something newer so that it's more reliable.  If we're there, it's a good time to opportunistically improve the experience if it needs it.. so if anyone has suggestions for the Client Checklist editor, now is a good time to add them to the Tax Idea Exchange.
