I have just given some suggestions from the view of a user of GRASS on 
how to improve it GUI further.
My response is below:

I just gave the suggestions that came in my mind.

By "window flooding" I meant exactly the same, for every module there 
is a separate GUI dialog which becomes very untidy and then every dialog 
has to be closed manually. What I thought about it is we can make a 
single gui which has a fixed widget to display the image, and every 
image will be in a different tab. Even if one launches a module from 
command line it will open as a tab in the integrated GUI. We will also 
give an option to the user if he wants to open the module in new window. 
This was the idea of an integrated GUI.

Swipe feature will be a new dialog that will have to widgets lying one 
on another having an image each. The width of the upper widget will be 
resizable from zero to length of bottom widget, the bar adjusting the 
width will act as a slider. This feature will be very useful in 
comparing any two layers(pictures at different timestamp). To implement 
this in wxPyhton is not very tough according to me. You can see it 
implemented here 
PostGIS manager was yet another idea, like a PostGIS manager in Quantum 
GIS. PyGreSQL is a python module that allows easy use of database 
operation API from a pyhton script. So it will be like a wrapper over 
the database. This can be done using wxPython and will be OS

All these were the basic ideas, for deciding the one to propose for 
SOC, I will need a mentor and feedback to guide me and make a proposal 
from the ideas.
