UI: suggested mockup for new gui
I don't know if you planned to remordenize the gui for this app (I honestly hope you will, I must say). If so, I'd like to submit a "mockup" that I came up with. latex.zip
It's incomplete, but it might give an idea of how your app could look like.
I don't know if you are already discussing about possible design or whatever. I made this file for fun mainly, but I also believe that showing some sketches could help in refining a concept for the final gui you will come up with.
I am glad to give more details if asked. I'm not a "pro" in using glade so I can't fully show my ideas using that tool yet.
