No color options and difficult customizing I couldn’t find the menu where to set individual colors and the drop down menus are all greyed out. Also the process of card customizing/making took some time to understand and a look at the manual. However, you can make a simple card game with this application and the hints for cutting and printing are nice.
デベロッパの回答 、 Thank you for your feedback. The "grayed out drop-down" that you describe is the default table cell move handle. It looks a lot like a hamburger menu icon. With that handle you can rearrange the vertical position of the field within the card template. When rearranging the fields of a deck, the values of the cards are preserved.
Version 1.5 added a Style Editor to change the colors and layout.
