#= for variables where two way binding is desired, make them a Ref in the struct

    checkbox::Ref{Bool} = false
    ImGui.Checkbox("label", checkbox)

for variables where view should be ready only, keep them immutable in struct but then passed as Ref to function

    checkbox::Bool = false
    ImGui.Checkbox("label, Ref(checkbox)) 

Or can put a changing value inside a -mutable- struct and use @c syntax

    checkbox::Bool = false
    @c ImGui.Checkbox("label, &checkbox) =#

Base.@kwdef struct MyModel
    messages::Vector{String} = []
