I noticed that you can't simply add an instruction in IDA. Yes, you can modify one, but not add(maybe there is such feature? Can't find it though). So I used HxD to forcibly increase the PE binary where I wanted with nops to then change the nops with what I wanted in IDA. However, I realized that screwed up all the calls and jumps that came afterwards. My question is then, how should I go on about adding instructions in a binary file? Specifically a PE one in my case. Thank you.
