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

So the major part of the image is taken by instances of Bitmap.

Interesting....
 

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...
