I was finally going to play around with the menubarplugin. Now I discover there is no documentation on how to add custom items to it, neither in the plugin itself, or on Github, or on
tiddlywiki.com. The release is the only place that even mentions it. And only two posts in this group. So there is an opportunity for those inclined to beef up the documentation.
I created a tiddler tagged $:/tags/MenuBar, and added a description and set is-dropdown to 'no'. For the text field and content, I inserted a bold text site title and a link to the index tiddler
''Dave's ideabase'' - <$link to="index">{{$:/core/images/home-button}}</$link>
Part of the problem was stylesheet related, which I can figure out myself. But now I get the following results:
1. Link to index does not open index tiddler.
2. Stylesheet changes to color of home image change in sidebar but not in menubar. Important, because hovering over element in menu turns background white, and thus the home image is white on white.
