I think that is pretty easy with some spec models.
Maybe there is already an example

yes, but a few models means a few classes :)

in a single class, it will e a lot easier glamour (which btw, is specially designed for that: to make browsers).

You can work with ready made models like ListModel/TextModel and just need one class for sticking them
together. Here some code, evaluateable from workspace, that shows how we
can build a "simple browser" with spec models:

This is just the simple skeleton, for more details it would be a bit confusing doing all this
in one workspace "script" :)

class:=Morph.
method:=class>>#openInWorld.

composed:= DynamicComposableModel new.
composed instantiateModels: #(code TextModel protocols ListModel methods ListModel).
composed code text:method sourceCode.
composed protocols items: class protocols.
composed methods items: class selectors.
composed code aboutToStyle:true.
composed code behavior:class.
composed title: class asString.
composed code acceptBlock:[:text |
    class compile:text notifying:nil.
    ].
composed protocols whenSelectedItemChanged:[:item |
    composed methods items:( class selectorsInProtocol: item)
    ].
composed methods  whenSelectedItemChanged:[:item |
    item ifNotNil:[
    method:=class methodDict at:item.
   composed code text:method sourceCode]
    ].
composed openWithSpecLayout:(
SpecLayout composed
newColumn:[:c | c
     newRow:[:r | r
        add: #protocols;
        add: #methods
        ];
    add: #code];
yourself).

Hilaire asked for a simple Method editor and
i wrote a simple example build with DynamicComposableModel, search the Mailingliste.
