[Feature Request] Automatic encoding/decoding of secrets in edit view

[patrick-pt]

Currently the Specifications tab for a Secret shows the decoded values of its keys, while the Edit page shows the base64-encoded values.

This means that editing a secret in Kubernetic involves encoding the new value elsewhere, then pasting it into the editor.

It would be nice if Kubernetic's edit page for a secret provided the option of a decoded view of the values of each key, with automatic re-encoding upon save.
