+ViewToolbar buttons can now be conditionally displayed based on the currentTiddler using a `condition` field. Similar to how `$:/tags/Exporter` and `$:/tags/EditorTools` already have. An example would be:
+
+```tid
+tags: $:/tags/ViewToolbar
+condition: [<currentTiddler>type[text/x-markdown]] [<currentTiddler>type[text/markdown]]
+```
