Expected behavior

Yep, the issue is that processing all feeds beforehand takes about 1 second before the feed loads. If we do it while scrolling, it creates a "bump" every time a new note is loaded. If we do it async, then the note shows with a number that decreases after the calculations are done, like 10 -> 0 replies, which is weird.

The new caching system I am building will resolve this issue with an intermediary layer of what's visible. But It might take some time to get ready.

I suspected that the filter was done after entering a thread, since I see some replies and then disappears.
Cant't the events be filtered as soon as they are fetched? The hidden words filter doesn't target specific fields, so it could be safely applied on the raw json.

However the async solution is not bad, just don't show the count immediately and fade it in when it is ready.
