Hi @linonetwo there's no support for that at present, but there's nothing stopping a syncadaptor from adding a view template segment with a loading indicator driven by its own data.

What does view template segment mean?

Is there an API to update the title bar of a tiddler template programmatically? I think this is a little complex.

Seems there is a new syncer, will it handle tiddler level loading indicator?

I think we can check _is_skinny and use a cascade for this.

Done in tiddly-gittly/itonnote-plugin@fe10d9b in itonnote-plugin, build-in in TidGi app.

Hi @linonetwo that implementation looks good – albeit I don't recommend using embedded stylesheets in that way.

I'd be happy to see this functionality in the core. I would handle the animation slightly differently, using a similar technique that the tiddlywebadaptor uses for animating the cloud icon.
