i would change

    local
    info := Data, Data := {}
    for _, pair in StrSplit(info, "`n") {
        pair := StrSplit(pair, "=",, 2)
        Data[pair[1]] := pair[2]
    }

to

    local
    info := Data, Data := {}
    for _, pair in StrSplit(info, "`n") {
        pair := StrSplit(pair, "="," `t", 2)
        Data[pair[1]] := pair[2]
    }

since when you write to file some variable it will add "space" between "=" and value ("name= value" instead of "name=value"), and then when you will load it it wont remove that unncecesary space and might cause problems when comparing.
