Your job is awesome!
Presets is a great idea, but now it's not perferct. I wanna save my own presets to face different situations, and maybe share my presets to other people.
And i found another issue which is can't save the advanced options. Standard options perfectly saved, but when open voukoder again, the advanced options become default setting.
That‘s all. Thank you for your contribution.
PS. I hope my poor English didn't bother you
