UI improvements for encryption and OMEMO keys

[zecamigo]

Hi there

I'm using Dino as a secondary client, the primary is Conversations. This means I use it less often, sometimes less than once per month

After a friend lost their OMEMO keys:

• there was no indication their keys had changed (they were previously accepted in Conversations, I only got the "user does not trust this device" message
• apparently because of that the first message I sent was unencrypted?
• there was no warning I was about to send an unencrypted message
• I had to squint to verify the tiny red icon indicating it was unencrypted

This happened to be a message with sensitive content. I would have expected something like a red flag and warning in caps lock.

The UI should be really more clear on whether encryption is on and what kind. (similar to #1240). The little open/closed padlock icon doesn't cut it.

Sorry to say I consider this a critical reason not to recommend Dino to anyone who really needs the privacy provided by OMEMO.

I love Dino though, please fix it.

/close as duplicate for "omemo by default"

Also, in Dino, pls toggle off "accept new keys" if you wanna verify

Thanks for the tips.

Please note this isn't about the behavior, it's about how it's communicated to the user through the interface.

Now I know HIW, but future users may face the same issues if the interface isn't improved. Even I can possibly miss this again because the padlock is tiny and my vision isn't perfect.

I don't always need OMEMO by default or to manually verify keys, I need an interface that visually helps me detect these changes and take action if needed.
