Add waitForValue

[giovannyquin]

Hi, first of all, thanks for your commands.
In fact, this comment is not a found bug else a suggestion.

Could you add the command waitForValue, that has the same functionality that waitForText, the change is just change getText by getValue.

I had an scenario where a form is populated and one input text shows the value after a service responds.

I think if you add that new command would be great, what I did so far was create the command locally but I think if you add the waitForValue command many people could benefit.

Thanks
