We will surely consider your suggestions but cannot give any timeline on this.
Also, for Silverlight part, you need to install Trident with the Silverlight option selected to see the Silverlight version of the Trident Composer which runs in a browser. This implementation is very basic and does not provide all the functionality offered
by the Trident Composer.
Also, as an open source the Silverlight client is available which you can download from the
Source code tab. You can work on this default implementation and may go further to customize at your will, for example to work in under SharePoint or MS Office.
The Silverlight code is placed under..\tridentworkflow-63690\Trident\Product\TridentWebClient.
Please let me know of any questions.
