Thanks for the suggestion.

The feature currently provided by mousetweaks to not consider little 
pointer movement is far from being a real tremor reduction feature; 
in fact, it only works during dwelling.

To implement a tremor-zoom feature that deserves its name, we would 
probably have to implement a real tremor reduction feature (that we 
currently not know how to implement) and the zooming feature.

The idea of the tremor-zoom itself is interesting and might be a 
candidate to consider for addition to the ToDo list, behind the 
single click feature already suggested by somebody in the 
Accessibility Ubuntu forum. On the other hand, as GNOME already 
offers zooming, the question arises whether it could not be simpler 
to add it there.

For the moment, the priority of Gerd and me is to get mousetweaks 
with its current features into GNOME.

However, if somebody is going to provide a patch to add a working 
tremor-zoom function to mousetweaks, we will be glad to accept it.
