Description
Steps to see the issue:
1) Go to Qt Creator's Preferences -> Help section
2) Remove all the auto-detected Help entries (picked up from my online installer Qt versions)
3) Save
4) Quit Creator
5) Open and go back to the help settings
6) Observe that all auto-detected help entries are back
Reason for feature:
I have many Qt versions installed with help files (15+) and startup of Creator is very slow because of it.
Possible UI:
In Preferences -> Kits -> Qt Versions when selecting a Qt version, show an additional checkbox that allows not registering that particular Qt's version help files.
Profiling:
I just ran Instruments on my Qt Creator, and here's some data:
