Thanks Ton,
That is exactly what I wanted. It showed up in my top-toolbar and there is now a checkbox the toolbar settings page to turn it on/off.
For anyone else who wants to do this:
Add the tag "$:/tags/TopLeftBar" to the tiddler "$:/plugins/danielo515/tiddlypouch/ui/sync-flag" in the empty NoteSelf file (the one that is hosted on a web server) before setting-up the Cloudant/CouchDB.
You may also want to set the "caption" and "description" fields in "$:/plugins/danielo515/tiddlypouch/ui/sync-flag" since those are used in the toolbar settings.
Note: If you don't understand what I wrote above, you probably don't want to do this. :-)
