I'm starting using Chinchilla a few days ago and tried to find a way to scale the minimap without scaling any of the icons, buttons, objective/Tomtom arrows etc ...

Is there a feature that I wouldn't have found which would do that ? If not, could we think about its implementation ? :)
Is this a bug ?

Edit: I (finally) had a look into Modules/Appearance.lua and noticed the commented lines about blipScale.

Found the following commit 723a849#diff-c456b3404b9b879dd7820231a1dc385a which title is

Appearance: Remove the blip size option as it is causing issues elsewhere.

Do you have any information about the issues caused "elsewhere" ? I'm keen on having a try debugging it.
