Or at least it seems so to me this function has been lost but perhaps I don’t see it.
I used to do it by pressing Enter (to go to Fullscreen Search Window) and click Latest.
Focus on a thread was preserved.
For example I’d like to display latest posts containing the word “mod” in a thread
[Tool] Grim Internals - Utilities and Resources - Crate Entertainment Forum.
There are far more results than the ones displayed in the Small Search Window (to about 300th post).
Going to Advanced Search loses focus on this particular thread so that doesn’t help.
Maybe that’s the bug and how I should have titled this report - Advanced Search loses focus on a thread.
