It would be cool if the user tasklist toolbar was 
configurable.
I think that should be as simple as going to the layer 
files and
defining a new folder under the Toolbars directory on the 
system
file system - and then reading those folders when deciding 
to create
a toolbar for each window.

E.g.
  Toolbars
     User Tasks
         NewTaskAction.instance
         FilterAction.instance
     Suggestions
         FixAction.instance
         GoToSourceAction.instance
         FilterAction.instance

The advantage of this is that userrs can modify these 
folders
(using the Options window and drilling down to the 
Toolbars folder)
or I think it's also accessible in an explorer you can 
show by right
clicking on toolbars. -- And when you do this, the folder 
modifications
are persisted. So you can cut & paste an action from the 
Actions pool
and paste it into the toolbar, and it's there from now on.
