Yes, I have something like this to handle development/deployment stuff.

only see application registration/modification using the default dispatcher.

But what about adding my own dispatcher? Like you can do via config panel in 
localhost:8080/config -> add .-> type (Dispatcher)

I need dispatchers, for example, to have /something_here/ as a dispatcher 
(not an application) so I can handle it, have its subapplications, and so 

So what I would need is something like register:at: but instead of 
applications, a dispatcher.

ATM, I only know how to create a dispatcher, and manage it, add/remove 
applications, debuggers and so, but nothing about telling seaside to 
actually use my dispatcher on a given entry point as string :(
