I am no longer able to see my boosts in my profile since 3-4 days now.

Is this a general issue, or is there a problem with my profile?

While using kbin, I realized that I keep going back to a Lemmy instance because it lacks two important features Lemmy (and Reddit) have:

• Collapse comments
• Quick preview of text, images and videos (single click to thumbnail)

Can this be added or is there a browser extension available adding these features?

I know there are many more features which are requested or planned, but these two are important basic features what makes browsing the community easier and quicker.
