#1 Seems like many things in the help file index are not in the "Contents" - as the "Sync" button doesn't work.
Might be nice if Contents was more complete.
#2 The Slick "C" api functions, (in programfiles\slick\h\...) seem to be in the index but their categories are wrong.
For example vsLoadTemplate.
In slickc.h:
* @categories Window_Functions
When you goto this page in help from the index, at the bottom: (qthelp://com.slickedit.texteditor/doc/api/vsLoadTemplate.html)
Category: Window Functions
But, clicking on "Windows functions" takes you to a page that doesn't mention vsLoadTemplate.
qthelp://com.slickedit.texteditor/doc/api/Window_Functions.html
vsLoadTemplate is on the page "C Window functions"
qthelp://com.slickedit.texteditor/doc/api/CPP_Window_Functions.html
I think all the "C" functions are categorized a "C ${Category:}", but their references to categories aren't also prefixed with "C".
"C Window functions" can only be found by search. (Oh, it is in the index as cpp_window_functions, but who would ever think to try that?)
