You can do everything but a reader wouldn't recall which widget you're talking about unless S/he digs inside this page :-)
(And I assume you weaken the main kw you're targeting for if not written in H1.)
The title tag is for search engines.
H1 is the title for the readers and for the search engines to value.
I agree that I should try to include the keyword phrase in the h1. If I don't, I am not sure that the reader will know what I am referring to.
I also agree that the title tag is for search engines, but I just wanted to mention that the reader can see it at the top of the browser and this can help to give them an idea of what a page is about. But I am going to take your advice and try to include the phrase in the h1 because a reader will probably look at the top of a page to see what is going to be discussed.
Also, thanks for the advice on repeating shorter phrases and using more caution when repeating long-tail ones.
