</div></div>While I see your point, how would you handle calligra active that has one<br>
interface for three applications at once?<br></blockquote><div><br></div><div>Calligra Active is a special case. It would likely sit on the the top level with the other applications and like to their core libraries. I think it's better to have one exception than completely changing all the others.</div>

And how would you handle Words and Author that share core functionality?</blockquote><div><br></div><div>Maybe an extra folder wordprocessing and in that folder Words and Author as seperate uis for the wordprocessing core. </div>
