Sorry for already making my third suggestion, I've got way too much suggestions for small stuff but I don't want to be banned for spamming LOL, anywayssss
I feel like the minimap's colours are extremely vibrant, some people may like that, but I'm not really the biggest fan of it. My suggestion is that there could be a few presets, one being the one as it is right now, one in the colours of a map perhaps, and one being the colours of the actual blocks. Maybe also making it possible to edit this via the use of resource packs. (Because who wouldn't love RDR2 coloured minimaps)
Another thing I'd suggest with this, is a world map. Now I hear the lot of you say "But isn't that an unfair advantage?", to which I reply to, no. If handled correctly, it can be extremely handy to have on survival maps or just big builds. The way I feel it could be done is taking inspiration from Xaero's Minimap, this map mod doesn't add any unfair advantages like being able to see underground, not being able to see other players or mobs, but just keeping it simple by seeing what you've explored so far. Maybe this could be integrated into the Minimap mod or anything like that?
