Hello!
Wow, so many replies in such short time.

I'll write a cumulative answer, thanks to all repliers!
The requests "don't use registry", "adjustable burnspeed" and "multilanguage" are already on the ToDo-list, that's the next things I'll implement.
Using the lister to display the documentation: okay, just implemented that. When you press F3 on the **Show Help, it will put the contents of the Documentation.hmtl in the lister window now. I hope that's what you wanted.
Over time I'll also add more functionality to the standard TC commands, e.g. some more built-in quickhelp when pressing Alt-Enter on commands/directories.
About not working download: it could be that in some cases this download counter thingy I'm using isn't working properly. In that case, please use this direct link:

About Opera: I'm using Opera 7.51, and the page loads all okay. What exactly is the problem?
