To make it possible to put the labels in categories.
I love this app, but I'm missing the possibility to put the labels in a categorie. I hope you can realize that.
I found out how to do this in Safe in Cloud. Instead of naming them categories, they are called labels. I can create all the labels I want and move the cards into those labels. This accomplishes what I wanted. It makes it easier and quicker to find some cards. Especially ones I don't use very often.
