We appreciate you using Piktochart for your visuals. :) We have an excellent alternative for grouping your saved visuals. This is a feature to help you quickly find them. We don't have folders at this time as a feature, but we're working on improvements constantly for you.
Click on the Search Saved Visuals to enter the Name or Title. A great tip is to name it something similar in groups with a similar word, letter, or number to identify it easier in search. Let us know anytime you need help with this feature. :)
