I have a problem that keeps the plugin from being used in our system. If you have included a puml graphic in a markdown file and change this graphic, the markdown file will not be re-rendered. I think it is because the markdown file and therefore its checksum does not change.
It would be nice if you had a "reload" button in the upper bar. And if you could configure a maximum validity period. For example, after a day of reloading the Confluence page, the data will be re-rendered.
