One of my favorite things about private servers is being able to change my characters appearance. Not sure how hard it will be to add but just a suggestion. For those who don't know what I'm talking about: It would be great for donors as well so they aren't limited to what hair styles they would like to stick with.
I've never seen that before, could you explain more what it is and how it works some? Maybe some links to where it's implemented like in GMS or something. I'm personally all for the idea of being able to save donor hairstyles so this is interesting.
It basically lets you save different combinations of hair/face and allows you to switch between them whenever you want. I don't know if it's possible to implement a beauty salon system here but it'll be awesome if you could change donor face/hair that you've bought already using mesos without having to spend rp again so you have the freedom to switch styles.
I couldn't find the GMS page that contains the update but here's a MapleSea's: http://www.maplesea.com/news/view/introducing_the_beauty_salon_system/#sthash.rjo7XXJx.dpbs It also includes saving features such as different eye styles. Upgrades can be purchased using reward points which can be obtained from killing bosses. I guess you can use the same system here as well (boss drops hairstyle slots).
