It has potential, it needs to be worked on.
The display in the form of a list is missing (important - it should have been at the beginning), as well as the display of the name of the icons (important - when two icons are the same - how to quickly distinguish between them?). It also lacks subcategories and other features.
Good idea (4 tacos), very simple implementation (I'd rather not rate this). Why didn't you make it the way of web browser bookmarks?
I hope it will improve in the future. If not, it will be wasted money.
