In the RM Web transaction view, I can scroll through a long list of categories and check them to add each to the filter. However, it can be difficult to know which items are checked because the list is quite long, and the drop down box is rather small. I think moving checked categories to the top of this list would help with visibility. For example, if I checked "Travel & Vacation" It should be moved to the top of the list above the unchecked categories. Alternatively, the dropdown could be replaced with a large dialog box with a grid of categories, so they could all be visible in one screen. A check all / uncheck all button like in mobile may also help.
