A new version is available (0.3) which gives feedback on save and allows to create pages indeed (via a separate button for now but having a create option directly in the search dialog could be handy indeed). This version allows also to open pages from the current wiki rather than the main one, as long as the path-based scheme is used, and to add or remove attachments (the removal requires reopening the page for now though, that’s because the application currently expects that the REST API returns the name of the removed attachment, which is not the case at the moment in the XWiki REST API, not sure what’s the recommended practice, to be investigated).
Next possible steps: ability to edit XWiki objects possibly in YAML, and extension points mechanism for allow to add features or to customize the apperance. Any feedback or suggestion welcome :–)
