[Lazarus] UI Design Question

[Leonardo M. Ramé]

Hi, this is more an application design question than a Lazarus related
one, but, since I'm developing with Lazarus, I'll ask here :-).

My app has different ways to show medical data, I call each a VIEW, that
let the user do different things with the data. Deppending on the
selected VIEW, the user will see different toolbars letting him to
interact with the data. Each view is implemented by using the "abstract
factory" design pattern.

Now, I'm looking for some ideas on how to implement the toolbars or
toolboxes for each view.

Currently I have three toolbars that I show/hide for each selected VIEW,
but I don't like this approach, the more toolbars I add, the more messed
my UI gets. To solve this, I'm thinking on creating many TFrames containing one 
toolbar each (and one TActionList also), and create an instance of the needed 
one when a VIEW is activated. 

How would you architect this?
