Thanks. Cuis should include an English spell checker to validate 
comments and strings... Maybe method names too!

Yes. If you remove the desktop background and reduce the color depth of 
anti aliased fonts, you can reduce the image to about half the size. See 
#reduceCuis. In addition, it is very easy to disable the autocompletion 
mechanism and save some space used by TrieNode and TrieLeaf. BTW, the 
autocompletion implementation is really one of Cuis' "best kept 
secrets". Just check it. It is way better than ecompletion and 
ocompletion, and it would deserve to be adopted for Squeak...
