Allows you to instantly restart any simfile mid-game, without having to back out of gameplay.

Place QuickRestart.lua as Themes\Waterfall\BGAnimations\ScreenGameplay overlay\QuickRestart.lua

Once done, load QuickRestart.lua by adding af[#af+1] = LoadActor("./QuickRestart.lua")
to Themes\Waterfall\BGAnimations\ScreenGameplay overlay\default.lua's AF in a way that resembles the image below:

You can change which key(s) is/are used pretty trivially (with a small bit of lua knowledge) by modifying the lua file if u like

Place tick.png as Themes\Waterfall\Graphics\tick.png
Place MusicWheelItem Song NormalPart.lua as Themes\Waterfall\Graphics\MusicWheelItem Song NormalPart.lua

Alternatively, if you would just like to display your ECFA number instead of texts and/or ticks,
Daikyi has made his own version of the music wheel item normalPart.

The color of the number indicates the type of clear you got on this song.
This only applies to songs in the ECFA folder, non ECFA songs will use the standard clear text display.
It's also difficulty agnostic, so it will always display regardless of which difficulty you currently have selected.

Note: This is not compatible with the tick (Mod #3) at all, but you'd still know if you haven't ECFA passed since the number is 0!
Place MusicWheelItem Song NormalPart.lua as Themes\Waterfall\Graphics\MusicWheelItem Song NormalPart.lua

(You don't need to turn FA+ to view the number, I just used this to show where it shows up onscreen.)

Place JudgmentNumbers.lua as Waterfall\BGAnimations\ScreenGameplay underlay\PerPlayer\StepStatistics\JudgmentNumbers.lua

Note this is an ECFA DP out of total notes hit so far, not total notes in the song.
I tried making it total notes in the song but ran into issues trying to get the total number of judgable rows,
as opposed to the individual number of hittable notes.

(Basically, the case of determining whether hands are hands because they are two arrows with a hold, or three arrows,
was throwing off my counts with various different counting methods.)

UPDATE (Mar 13 2021): Fixed bugs with ECFA DP counter when using ITG mode, and fixed hold count errors.
UPDATE (Mar 13 2021, again): Added Laplace's green coloration on FA passing. If you do not want this, delete lines 309 to 313.

You can move the in-gameplay timing dashes to the side of the judgments with this modified EarlyLate.lua
It goes in Themes\Waterfall\BGAnimations\ScreenGameplay underlay\PerPlayer\EarlyLate.lua
Note this only affects timing dash, not the Tony Hawk (Error) Bar or the EARLY/LATE text.
The bar properly respects mini usage, reverse usage, etc.

UPDATE (Mar 12 2021): the modified EarlyLate.lua now properly respects step statistics in 2 player mode.

		
			if style and style:GetName() ~= "single"
			or notefieldwidth and notefieldwidth > _screen.w/2 then
				table.remove(choices, 2)
			end
		
		

				
			if notefieldwidth and notefieldwidth > _screen.w/2 then
				table.remove(choices, 2)
			end
		
		

This will allow you to select Step Statistics from the Player Options page 2 while in Versus (2 player) mode.

Then, add the actual objects themselves to your theme by:
Place VersusStepStatistics.lua as Waterfall\BGAnimations\ScreenGameplay underlay\Shared\VersusStepStatistics.lua
Place BackgroundFilter.lua as Waterfall\BGAnimations\ScreenGameplay underlay\PerPlayer\BackgroundFilter.lua
UPDATE (Mar 12 2021): Place EarlyLate.lua as Waterfall\BGAnimations\ScreenGameplay underlay\PerPlayer\EarlyLate.lua
Place JudgmentNumbersVersus.lua as Waterfall\BGAnimations\ScreenGameplay underlay\PerPlayer\StepStatistics\JudgmentNumbersVersus.lua

Once done, load VersusStepStatistics.lua by adding t[#t+1] = LoadActor("./Shared/VersusStepStatistics.lua")
to Themes\Waterfall\BGAnimations\ScreenGameplay underlay\default.lua's AF in a way that resembles the image below:
