Error display on the viron screen

Is your feature request related to a problem? Please describe.
現状、APIから返却されたエラーが画面上で確認できないため、エラーに気づきづらいです。

Describe the solution you'd like
以前のvironのようにポップアップなどでエラー内容が表示されると良いです。
ポップアップでなくとも画面上で確認できることが理想です。

Facing the same problem operating viron for a large scale mobile application's admin tool.
Currently, there is no feedback for a failed operation (CRUD). Say a create operation fails on the API side for whatever reason, the only feedback is that the new content hasn't been created.
If there could be at least an generic js alert or a popup as the original issue suggests, it would make things much easier.
Thanks for your consideration, and a great open source application so far! Cheers.
