ShareAdd.jl can be combined nicely with BasicAutoloads.jl by @Lilith .

Here is my current `startup.jl`:

```julia

if VERSION >= v"1.11" && isinteractive()
	using ShareAdd
    import BasicAutoloads
    BasicAutoloads.register_autoloads([
    	["plot", "scatter"] => :(isdefined(Main, :plot) || @usingany Plots),
    	["DataFrame", "combine", "transform!", "transform", "select!", "select", "groupby"] 
    		=> :(@usingany DataFrames),
    	["CSV"] => :(@usingany CSV, StringEncodings, DataFrames),
    	["Dates", "Date","DateTime"] => :(@usingany Dates),
    	["mean", "std", "median"] => :(isdefined(Main, :mean) || @usingany Statistics), 
    	["@u_str"] => :(@usingany Unitful),  
    	["@benchmark"] => :(@usingany BenchmarkTools),   	
    ])
    println("ShareAdd & BasicAutoloads are loaded")
end

```

Now, should I e.g. type `mean([1,2,3])` or `1.55u"V"` in the REPL, Statistics.jl or resp. Unitful.jl would be first silently loaded.

The “main” shared environment, i.e. the folder “~/.julia/environments/v1.11/” contains now only `Revise`, `ShareAdd`, and `BasicAutoloads`. Most “shared” packages are each individually in the eponymous env, like `Plots` package is in `@Plots` shared env.
