As someone who uses the Customise Your Lion and Create a Custom Lioness feature all the time, I have noticed something that I find rather inconvenient when I am creating a custom lion:
The opacity for all the marking slots in the Oasis customisation are automatically set at 0% when you first open it up to create a new lion/lioness. I think this should be changed so that they are all automatically set to 100% opacity just like how it already is in the wardrobe.
Reason why is because the first thing I (and I'm sure plenty of others as well) go to do after opening up the customisation is add a marking to see what it looks like. I would like for that marking to actually show so I don't have to sit there confused for a minute before I realise all of the opacity setting are at 0% and I need to go in and change them all first to see the marking I just put on my lion. It makes a lot more sense for them to start out at 100% opacity, because most people decide on what marking they want before they decide what opacity they want the marking to be at, and you need to be able to see the marking at full opacity to know what you're working with.

I just find it inconvenient that I have to go and manually change all the opacity settings to 100% before I can start trying out markings on my lion. Just a simple adjustment. Hope that makes sense and thank you for reading!
