ThunderBoard beta 6

The default theme should work. However, due to the intrinsically unstable nature of ThunderBoard makes it unreliable on most custom themes (it was designed for MyBBoost’s previous theme only, and made progressively theme-agnostic, but other projects got higher priority).

Support is barely given today, especially because the current codebase has been replaced by a simpler version which is not released yet.

I tried but failed on original template. Maybe I will just wait the official release.
idk why this has not included original mybb core... Most forum softwares in these days they work very smoothly and exclude part of page from re-rendering when moving to another page.... so, fast.
