I am currently building workflows on unfamiliar data and using the filter tool on text fields regularly on a large excel file.
As there is no dropdown on the right hand side of the filter tool I find myself needing to open excel and use it's dropdown functionality to find the right text to filter on. I know I could use the summarise tool but each time I run the workflow it takes many seconds to complete before it is populated. It is quicker to use Excel. I am surprised this has not been requested before.
