A feature to set the process priority would be fantastic! As it stands right now, when my cpu usage is high such as when playing certain games, HONK tends to lag. The ability to set the process priority to high like you can in OBS would help mitigate this.
Animated GIFs would be fantastic as well, but I know it's already something that you have already mentioned and other people have recommended as well. Otherwise absolutely fantastic piece of software and I thank you for all your work!
