The new features are things like a source code thumb (see the entire source code on the right side of the screen for quick navigation), JIT information (argument types, function return types, expression value types), improved expression boolean result (makes it easier to optimize the order of long conditions), and a generally improved UI.
I've also upgraded it to use ZeParser2. Or rather, I've rewritten it from scratch using ZeParser2 :)I've uploaded some screenshots for your amusement ;)
Anyways. The current HeatFiler can be found on github
(or at the live demo
). Have fun with that in the mean time :)
