Request: Option to Support Rows and Columns within a Menu

[SuperBox64]

Just started using Flex-Launcher after finding so many input-key mappers what would work with Gnome's Desktop but then would over ride and interfere with the games that I am launching.

For my use case, I would like to show a grid on a each menu where the user can navigate with the game controller or keyboard and select the game or submenu to choose from. This way, They would not have scroll horizontally if the wanted the columns and rows instead.

Thank you for your time and consideration and where I can send a donation. Thanks!
