ooh theres that super confusing bug .. well another bug that im finding out about too late ..., if you tried to drag and drop file from explorer to the website then it wont work, but in the same time it will show that drop indicator which is confusing, I completely forgot to implement the importing on drop and in the same time I didnt remove that indicator, well stupid me, honestly I havent got many people to test it so it is what it is ;/
I tried to drag and drop a .PNG but it didn't work.
