Should we do it all the time (without props)? Or if href doesn't match content?

Then it duplicates already existing web-browser feature

I say we keep the same for all links

True. I couldn't find any related options or preferences in Electron app, but that anyway should be done in talk-desktop repo, I believe. Another point of doing that is that we have links outside of NcRichText (as conversation links, settings redirects)

Maybe we can implement it with a custom solution, like:

• add listener on hover
• if it's a link, draw a preview box in the corner
