Application: add button to show password

[Fishrock123]

This is very useful for manually entering passwords into devices that are unable to access derivepass.

Also fixes a silly warning display bug.

I suppose I could add more space between the buttons... I'm not sure how best to do so without making something custom though. Something about margins and negation via :first-child and :last-child...

Great idea! I needed this myself many times.

Do you think it might be better to hide it in "Edit" so that the user won't accidentally reveal the password? Or should there be a confirmation?

[Fishrock123]

Yeah I wasn't quite sure either. An extra confirmation could be good, I suppose.

What about using a button group for those buttons?

I'm not very familiar with Vue. I'll take a look soon.

I'm talking about the bootstrap's button group component: https://getbootstrap.com/docs/4.3/components/button-group/
