'windows smartscreen has blocked an unrecognized application'
rip 
nvm i got it. man this thing is amazing, is there a special window for HS checking or does it just tell u if there is a hitsound with delay?
suggestions:check the image size of the background and sb elements (1366 by 768 for bg, etc)
display a warning for low hitsound volumes (below 20% or something) it might not be unrankable but it is definitely useful to know where those timing points are on the map so we can go check it ourselves without having to find it
also not sure if this is possible, but check the video dimensions since i believe the max is 720p for osu (and video offset if that isnt in there already)
inconsistent kiai/endpoints (ending time of difficulty that is)
spinner recovery time guideline thing (easy 4 beats normal 2 beats hard 1 beat, so on and so forth) (uh i think u can kinda scan the difficulty name and etc, or star rating. dunno how u can do this, maybe kinda hard to implement)
