[54:45][@Flederfalter][I don't understand why a single if-statement would be expensive if we do it at runtime. Can you give an example?]
[1:07:54][@elxenoaizd][Why are we adding // b32 comment in the config file?]
[1:08:30][@TheSizik][Can you toggle the debug options while looping?]
[1:09:41][Separate out the mouse handling from the recorded input][:"input handling"]

[1:13:06][@andsz_][You should add an optimization switch to the UI at some point]
[1:14:02][@andsz_][Wouldn't -O2 optimize those dead branches out?]
[1:14:41][@ingenero][Could you have an option to either recompile or simply toggle an "if"? It seems like most of the time you would use the regular "if" so the change is instantaneous, but in extreme cases you could easily just do the recompile option]
