1) Not yet, we are hoping to address this for the 5.0 release.

Carol I would encourage you to download MyEclipse and try it for a month and see if it does what you need it to do. You can get a feel by reading through our docs here: http://www.myeclipseide.com/ContentExpress-display-ceid-67.html
I’d also point out that with our money back garuntee you can email our subscription department after 200 days into your subscription and say “I hate this” and they will refund your money, there is no “oops you had it for 127 hours” kind of monkey business, we honestly just want everyone happy with our tool and if they aren’t there is no reason to lock them in.
