I feel like I'm missing something obvious here, but ever since 10.0, my Masque options just look like this. I can't actually select which skin to apply, it just tells me compatibility and information about the author. Before the recent changes, I was able to select different button elements and apply Masque skins to them. All my previous settings are still applied, but I can't make any new ones. Has the functionality moved somewhere else, or is this like a temporary limitation while the addon is updated? Thanks for all your work.

Edit: Oh... speak of the devil. As soon as I clicked another addon's options, the plus sign appeared to the left of Masque and I'm able to do everything as usual. I'm pretty sure this plus sign wasn't visible until I clicked another addon's options, so perhaps this counts as a bug?

I'm pretty sure this is an interface bug with WoW at the moment. Plugins that change their menu contents to have submenus don't show up until the frame is redrawn. I imagine it will eventually be fixed by Blizzard.

If you set the options to show the standalone Masque window it might be a bit more reliable for now. It can be pulled up with /masque.

Yeah, if the additional options don't show, you can either click the Game tab and back or click the + next o another add-on. As @kstange mention, you can also use the msq or masque chat command to open the window directly.

@eightflat I am curious to know how that happened in your case, because I made all of the options pre-load for Dragonflight users who aren't using the stand-alone GUI. Did you load via the Load Options button or some other way?
