Hi, thanks for the suggestions!
- Zooming: Maintaining central point is already in our plans, but we totally forgot about ctrl/command+scroll thing. Thanks for reminding us that!
- Hairstyle construction: We'll be adding an 'advanced' option with exactly that kind of functionality. Expect it to land after 0.2.x.
- Library catch-up: Advanced color is the main reason we are redrawing everything, but we also seizing this moment to re-adjust body proportions and the like; that's why it's taking a longer time. Currently we're not really satisfied with the overall art style produced in the stable version, and we have been taking references from our favorite digital artists (i.e. @rosuuri, @sayori_nw, and @Tony_T2ARTWORKS to name a few) for 0.2.x.
Glad to catch your interest and hopefully we'll be able to implement these as soon as possible :)
