Hi. Same question already asked few years ago but never answered.
How to define the "index" action is not the default one?
For now I'm stuck with a 404 page when trying to access my plugin which homepage should be a form for the plugin settings.
I tried to simply a duplication of my update.htm into index.html but it doesn't seem to work!
[EDIT]I finally found a solution after hours searching: I looked into some plugins code which adopts a similar structure as I want: just a settings page. Especially LukeTowers.GoogleDomainVerification: Settings page is is the october settings, which is imo a proper way to do. I get in trouble with some lines but I finally found the solution here
