do we need element.followingSiblingBy(tag: string, predicateOrCondition: string | Condition)?

[yashaka]

We have:

    get followingSibling(): Element {
        return this.element(by.xpath('./following-sibling::*'));
    }

do we need something like this:

    followingSiblingBy(xpathPredicateOrCondition: string | Condition<Element> = '', tag = '*'): Element {
        if (typeof xpathPredicateOrCondition === 'string') {
            return this.element(by.xpath(`./following-sibling::${tag}${xpathPredicateOrCondition}`));
        }
        return this.all(tag).elementBy(xpathPredicateOrCondition);
    }

The signature also might be like this:

    followingSiblingBy(options: {tag: string, predicate: string, condition: Condition<Element>}= {tag: '*', predicate: '', condition: undefined})

The argument to add is:

• give user the full power in a more concise helper

The argument against is:

• it will be needed rarely, why not keep things KISS, and for complicated rare things use just more verbose versions with .all('./following-sibling::div').elementBy(be.visible) or something like that) In fact our "powerful" helper will not be really more concise...
