When I hit the X button to close it, it kills the app even though I set it to run the system tray. Other apps just hide the window, and continue to run from the system try.
Not that big a deal, but I have the habit of hitting X since that is easier then going down to the tray and clicking the icon again.
It would also be nice to be able to move items from 1 group to another.
Overall I like it so far, I have only been running it 20 minutes, but I have been needing something like this to monitor sites that don't change that much.
Thanks.

make install shouldn't touch anything outside of DESTDIR. I'm specifically referring to the ln -s /usr/share/doc/HTML/en/common to somewhere else.

Thanks for the feedback. I think you are referring to these lines in kwebwatch/makefile.am:

$(mkinstalldirs) $(kde_htmldir)/en/kwebwatch
rm -f $(kde_htmldir)/en/kwebwatch/common
ln -s $(kde_htmldir)/en/common/ $(kde_htmldir)/en/kwebwatch/
$(INSTALL_DATA) $(srcdir)/index.docbook $(kde_htmldir)/en/kwebwatch/index.docbook
[...]

The Makefile.am was based off a template from the KDE2 days so it wouldn't surprise me if it could use some work. Any pointers to the correct and modern way to install kde documentation are welcome :-)

Doesn't kdevelop automatically take care of that sort of thing? Here's (imho) what looks like a good, simple example of how docs should be installed:

***./doc/en/Makefile.in***
$(mkinstalldirs) $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail
echo $(INSTALL_DATA) index.cache.bz2 $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/; \
$(INSTALL_DATA) index.cache.bz2 $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/; \
echo $(INSTALL_DATA) $(srcdir)/index.cache.bz2 $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/; \
$(INSTALL_DATA) $(srcdir)/index.cache.bz2 $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/; \
-rm -f $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/common
$(LN_S) $(kde_libs_htmldir)/$(KDE_LANG)/common $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/common
$(mkinstalldirs) $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail
echo $(INSTALL_DATA) $$base $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/$$base ;\
$(INSTALL_DATA) $(srcdir)/$$base $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/$$base ;\
rm -f $(DESTDIR)$(kde_htmldir)/$(KDE_LANG)/kcheckgmail/$$base ;\
***End***./doc/en/Makefile.in***

This was found by:
for i in `find`; do echo "***$i***"; grep DESTDIR $i; echo "***End***$i***"; done

AFAIK, kdevelop was designed so that one can code more, and worry less about these sort of things. I would imagine that the easiest way to get things up to KDE3 standards, would be to import your current workbase, deal with the kdevelop warnings, then export the modern GNU-tools source-package.
