Welcome, pferrrel. For the Sunrise preset, you're right -the exposure shouldn't be locked. Thanks for catching that. I'll fix that for a future update.
As for editing and assigning custom values, yes, that is the next step of presets which I'm working towards.
Thank you for providing feedback on this. It really helps to know how other people use features, because my own use and workflow isn't necessarily the preferred way all the time. 🙂
