The good side of the toolview is that you can see the same time the 
rendered and not rendered version.  Splitting might work as well, and 
sincerely I cannot judge which one would be better for the users.

The DTEPs are used to parse the document. After parsing a DOM-like tree 
is created. That is independent of the DTEP, that is a result of some 
parsing (as I understand DUChain is something like this tree). And the 
structure tree visualizes this tree.

I still think there is some confusion regarding the DTEPs. :) But it is 
not that important atm. Anyway, I see no problem if we provide a 
different toolview to navigate through XML and another toolview that 
shows the PHP/JavaScript/CSS/Ruby/whatever stuff.

Ok, that's fine.

No, I just meant that we need to make configurable actions, not KActions 
created upfront in the code. Regarding input (for the external script), 
that can be from the document (selection, whole document, document's 
path, project path). If the scripts needs user interaction, it is its 
job to provide an UI. That was in most cases via Kommander in Quanta3, 
but it can be anything, like a PyKDE app.

No promises, but maybe at Akademy I will find time to do it again for 
KDE4. :) So if you can get until the place where we can group the 
actions into logical groups (well, probably a KActionCollection), I can 
try to do again putting them on a toolbar.

Yeah, we have something on our server, don't know if that still works 
with KDE4's GHNS. What is important in that case, that there is a need 
to verify that downloaded scripts are from valid source. The idea was 
that they need to be signed, so the one who downloads can decide if he 
trust the signee or not. I extended GHNS at that time to support 
signatures, but I have no idea if this feature is still in KDE4 or not.

Yes, there were dialogs, and sometimes they are useful (think that even 
C++ language has dialogs/wizards). But autocompletion should be enough 
in most times, I agree.  For good completion, you need good parsing and 
understanding of the document. That's where the DTEPs came into, so 
Quanta could know what attributes are allowed for a tag, or inside a tag 
what other attributes were allowed, so when you typed "<" it could offer 
the valid tags.
 BTW, in case you didn't know, Quanta could do the following:
- typing a tag would fill up automatically all the required children 
tags. Eg. <ol> must have at least one <li></li>. So when the user 
finished to type <ol>, Quanta inserted 
- typing a tag inserted its closing tag. Eg <a> insterted <a></a>.
- if a tag was unclosed, typing </ would insert automatically the right 
closing tag.

Of course all these were configurable, but turned on by default. And I 
think it helps a lot with writing XML.  This is somewhat different from 
C++, there the most closest feature is the automatic insertion of 
closing paranthesis or quotation mark.

Yes, the good idea (although not completely working) in the editor was 
that you had a preview of the CSS.
