I tried to change as a first step the environment (adding my own layers and removing the ugly tables) using the following statement: <div id="divHeader"><div id="divCommands">+commands+</div></div><div id="divLeft"><div class="boxes">+tree+</div></div><div id="divContents">+contents+</div> But it seems, that this code gets escaped. Inspecting the kernel and its root structure I see my HTML code as part of a paragraph which seems to escape all the HTML characters... Help is welcome! ;-) Cheers, Chris
