I was unaware of changes to Beta 9 module editor API until recently working on a different module. The changes between 8 and 9 mostly killed the settings pane in this module.
I have updated the ShiVaHg package to rectify the problems and uploaded it for review, expect it will be available in a few days after approval.
Changed version number to match ShiVa2 version numbering while the editor is in beta (

)
Changed the functionality of the "browse" button. Previously it would launch the Hg web server and show a browser window inside the editor. This still works but now I can't hide that window again. So the Browse button will now immediately launch to external browser (your default web browser). Toggling the browse button back to disabled will kill the Hg web server.
