@acjay if you go visit their profile from their instance (it's a pain sometimes but you can usually click their profile picture to go there), then you can find that toot. Then you can copy the link to that toot and paste it into qoto's search bar. That'll pull up the toot via qoto, and you can respond then.
That is painful, right? But it does get better once you follow them for a little while.
@acjay I've thought it would be great to have a way for other instances to know what your home instance is... So that if you're browsing on another when when you hit "follow" or "reply" it can automatically use your home instance URL. A browser extension might be necessary for that, but it would be great to have something that could work with just existing browser features. I'm not sure if any cross-domain data stores exist, that don't rely on a trusted third party.
@finity Yes, exactly.
@finity Yes, this worked!
It would be cool to have a browser extension to make this easier.
