Thanks, Pratik!
IMHO, I think there should be also a panning tool (and its corresponding
pallete ToolEntry) which is separate from the selection, as this is very
common today and it might not come naturally for users to pan using the
space bar.
Also, a ready-made zoom tool, which of course uses the ZoomManager's
abilities, might be very useful.
BTW, I don't know how it works- when (if) I come aroung to writing such
tools, can I submit them as contributions for GEF?

Perhaps. It shouldn't be too difficult to write such a tool for yourself.

Another example of something that's not too difficult to do. However, I
think Ctrl++ and Ctrl+- provide sufficient functionality and demonstrate
well enough what can be done.

Certainly. I am not sure exactly how it would work either. I don't think
anybody has (certainly not in the time that I have been here) contributed
brand new code to GEF. But one way we can go about doing this is to have
you create a patch in Eclipse for the GEF plugin. We can then review the
code and decide on whether or not to release it to the GEF steam.
