Please add visual indicators for filters when they are active

When looking at data in Aha, many times there are filters that are able to be applied to that data set. 
The down side is that it isn't always obvious if a certain filter is 'active' or not.

Request: Is it possible to gently shade the filters if it is in use? (Use meaning that the filter is set to any other value than the default value). This would help alleviate confusion and be more obvious to the user that the dataset is being filtered and immediately draws the users attention.

I have provided an example of one screen below.
