My suggestions:

1. Clean up (remove obsolete plugins):

• jst.firstrun (This plug-in used to initialize AS and Data drivers during the first run. Has moved to runtimes component)
• jst.web.verification (Our old validation framework which we don't use anymore. All verification rules have been migrated to our common validation framework)
• jst.web.tiles/tiles.ui.

2. Fix dependency problem between jsp/html editor and other jsp/html editor related UI features (such as html5 property view) by merging all UI plugins into jst.web.ui plug-in:

• jst.jsp (JSP/HTML editor, content assist, outline)
• jst.web.ui (palette, wizards, ...)
• jst.text.ext (Open Ons)
• jst.css (css editor)
