but with the system as it is now this is quite difficult.  but this is 
already a bit easier than before (cf systemNotifier, new compiler...)

Not that much if you compare with the current average quality of squeak 
code.

But mike we cannot afford to rewrite it now and we deserve to have a 
better (rename class functionality).
So what we can do is use the best tools we have and later when we have 
the time rewrite them. For now we are quite
ridiculous compared with standard java ide for that level.

so in that case we should not have package in the base image. I think 
that everybody talked a lot recently but few
people really tried to do the work of marcus.
