For Abstract, Vincent and Artistic AI, to add another art style to the horizontal list on the bottom I have to click Add New, select the art style in the Open dialog and it appears somewhere in the list. Then I have to find it. If I have a large number of styles this can be a pain.
It would be much easier to simply apply the selected the art style from the Add New Open dialog automatically after adding it to the list.
This way I can organize my art styles into folders and use them without having to depend on the horizontal list unless I want to.
Also, when clicking Add New, it would be nice to be able to select more than one style at a time. In that case, multiple styles can be added to the list without automatic application.
Another approach would be to be able to select a folder and all styles in that folder will replace the styles in the horizontal list.
