Hello Aibarra86 !

1. Correct, but it looks like an untranslated key, what language do you use in your UNA?

2. You may change it in Studio->Polyglot app, Keys section. But you may change only the word "like" to keep the actual usernames in messages.

3. Like shown above - via Polyglot app. See more details here https://github.com/unaio/una/wiki/Polyglot

4. Will be added in the closest version.

5. Yes, it can be enabled but via database now, if you need it then just confirm
