Creating new topics for feature requests is a good way for us to keep track of them, and I’ve created tickets for your first two topics.
For your third topic, this seems like a small bug where the dropdown menu does not display the most recently saved algorithm preset. However, you don’t need to quit Emote for it to show up. I’ve found that just opening the menu a 2nd time will then display the most recently saved preset. Let me know if that works for you, but I will see if we can have the menu update in a better way so it will always display recently added presets.
