I don’t know whether you like criticism, but
1) It seems you can only show one tool window at a time? It would be nice if tere were a tabbed interface for the tools.
2) The fonts don’t look as good as in some other editors. I am used to Editplus (it doesn’t work so well on x64, hence why I am here). The fonts are very crisp for OpenType (e.g. Courier New, and Trebuchet MS). It seems there is some aliasing missing in EmEditor.
