Annotations - Text and Arrow?

Hi Everyone

I have a few questions about annotations.

I am using the 18.3.5 orthanc/osimis docker image on Ubuntu Xenial, with WVP_ENABLED=true.

  1. Are arrow and text and arrow annotations only available on the ALPHA build for the Osimis web, and consequently only Regions of Interest are available on the official build? This is slightly confusing as on the DEMO page, http://www.osimis.io/en/blog/2016/10/14/plugin-osimis-pro-viewer.html, the text and arrow annotations are available?

  2. On the ALPHA build, editing a text and arrow annotation seems to be broken?

  3. Is there a way to delete annotations?

  4. Is there a way to limit visiblity/access of annotations on a per user level? i.e. restrict editing/viewing of annotations to certain users only?

Thanks in advance!
