Things I miss in GNU Emacs

I appreciate everybody's input on the discussion on how to continue with
the project.  I personally would like to collect features that XEmacs
has but GNU Emacs hasn't and see what the chances are of getting them
included in GNU Emacs.  So if you have such a list, or just random
items, please send them to me or the list.

FWIW, my list so far has this:

User-visible features:

- Ben's HTML mode
- C-Left Mouse for pasting
- minibuffer-confirm-incomplete
- Marcus's incremental collector (slim chance ...)

Internal features:

- opaque datastructures for various things - keymaps
- menus separate from keymaps
- specifiers
- extents
- separate representations for chars and numbers
