Gameplay/Track builder mechanics I'd like to see on this website

Here's 6 things that I really want to see on this website, mainly relating to gameplay, complete with short explanations why.

Ultra Mini-Turbo
Right now the maximum drift charge is a Super Mini-Turbo, as with all Mario Kart games starting with Double Dash. As someone who's played a lot of 8 Deluxe (which introduced Ultra Minis), not charging Ultra Minis feels so off to me.

Custom final lap fanfares
I know. It sounds weird, but it can work somehow. For example, someone making an N64 track can change the final lap fanfare to the one heard in MK64. I'd like to see the preset fanfares be the ones from Super Circuit, DS, and 7 at least.

Mario Kart 64 track styles
I've always thought the only preset track themes being from SMK, Super Circuit, and DS felt pretty limited. If track styles based on MK64 are possible, then I'll be real excited.

Custom-shaped Dash Panels
Self-explanatory. I've been ACHING to see these.

Custom music in quick mode track builder
Also self-explanatory. I just want more custom music in my life

Arrow Fields
You know those sets of arrows in 8 Deluxe that only appear on the Tour tracks and Kalimari Desert that change position each lap? Yeah, those. It can make Tour tracks uploaded a LOT more diverse and accurate to their 8 Deluxe renditions.

Pretty short list, but I'll stick with it.

With the arrow fields, are you talking about the conveyor belt-like things in courses like Toad's Factory and those escalator-like things in courses like Coconut Mall?
Besides, a Mario Kart Wii/64 theme would be cool

Here are some courses I would add:

- Ultra mini turbos are not needed for mkpc. The game doesn't have the right scale for something like this, and the existing drifts are good enough. Plus, all records would have to be reset in TT mode. A lot of people have pretty much agreed that this shouldn't be a thing.

- Final lap music changes already exist (I think this is what you are talking about)

- People don't actually realise how highly requested new tracks are, and how much effort it actually takes to make them for the official game. Don't expect this to happen for a while unless Wargor gets help.

- Custom quick mode music
and different shapes of boost panels isn't necessary

- The arrows are a pretty cool idea, but may also be difficult to implement. It's also probably not too practical, so it is probably not gonna be a priority update

I think what he means about the 'Final Lap music' is the theme that plays when you start the final lap. In all Mario Karts it was a different tune.

a feature i'd really like to the complete mode track builder are holes that instead of respawning you at a certain place, they just respawn you at the last checkpoint you crossed

Why would they skip Double Dash? Wii/7 are way too complex.

I have no idea lol
MKWii is just my favorite Mario Kart, and MK64 was the first to implement 3D
And if you think about it, it wasn't all that hard to put MKDS in Quick Mode

Personally, I thought of some sort of "team" feature, where you could create or join a team with their own chat, invite other teams to battle or race and a team leaderboard for each gamemode. I'm not asking for this to be a feature,  I just thought it would be cool.

I want an Ultra Mini Turbo so badly!
