In my personal opinion, "Word Count" and "Spelling" should be in the Text menu, not in the Tools menu.
If this happens, the "Find repeated words" could also move to the Text menu, out of the spelling submenu.
Maybe one could also add
a Text menu item "Average number of words in sentences''
and a Text menu item "Frequently used words''
and a Text menu item "Frequently used expressions'' (of at most 4 words)
In an ideal world, there would also be a link to a Thesaurus.
These proposals comes from somebody who writes many long texts - if this is not the user you care about, put them aside. For a heavy writer, all the tools that concern writing texts could/should go in the "Text menu".
The first part of this proposal has been implemented like this:
Concerning the other requests, could you open separate tickets and specify more precisely what you expect. They are certainly very useful commands but in my opinion they are more specialised features which should go in a separate package which could add to the Window Utilities submenu (very much like the Window Lines package) .
Same with the Thesaurus idea: could you elaborate in a separate ticket? Note that the Www Dictionary package already has some sort of support for dictionaries and thesaurus.
Changes committed to the repository (rev. 1486 (sourceforge.net)). The indices must be rebuilt.
