Can a colon split a verb and the rest of the predicate? [duplicate]

Is this use of a colon incorrect?

I wrote an application whose features included: doing this, doing that, and doing something else.

If so, why? Is it because what precedes a colon must always be a complete sentence, or because—from Strunk & White—a colon should not separate a verb from its complement, or a preposition from its object? Or both?

Am I correct that the correct form would be simply

I wrote an application whose features included doing this, doing that, and doing something else.

Or even

I wrote an application that had many features: doing this, doing that, and doing something else.

The person I learned this rule from said, "Never put a colon after a verb." I looked it up, and yes, this is because you do not want to separate the verb from the rest of the predicate. Yes, it is also true about a preposition and its object. The two alternate ways you provide are both acceptable. The first one has the connotation that you care most about communicating what it is that your application can do, while the second one hints to your reader that what's really important is that your application has many features because the sheer breadth of them that your application is able to provide makes you the absolute mac.
