Idea Summary
IG and IR have different options when using Actions → Filter. From the user point of view, they should be the same.
Use Case
End users do not understand the difference between IR and IG.
Preferred Solution (Optional)
IG filter has a great option to create a multiple line filter before clicking Save to apply the filter. An IR filter can only add one line at a time, with a (long running) search every time you added one line. The IG way is the preferred way.
IG does not have the Row filter option, like IR. The Row filter should be available in IG too.
The Filter box in IG does not search for a value in NUMBER columns. IR does, which is the preferred option.
