Plain simple tables. But as I said problem will be in updating other 
panes (cells in that case) when you for instance select something in 
first pane (like in smalltalk browser). Try with calling many 
onClickUpdate: , each for pane which needs to be updated on such a 
select. Each pane is therefore an ajaxified element added to each cell 
of the browser.

For example:


   e := WebElement new.
   e cell add: self classPane.
   e newCell add: self protocolPane.
   e newCell add: self methodPane.
   e newRow.
   e cell collSpan: 3; add: self editPane.


  ^self panes at: #class ifAbsentPut:
    [| e l |
    e := WebElement new.
    l := some link to be clicked etc...
      onClickUpdate: self protocolPane;
      onClickUpdate: self methodPAne;
      onClickUpdate: self editPane.


Well, try something like this, but note, these are just some ideas right 
from my head and probably won't work "out of the box".
