[Feature Request] Add recently used icons.

[NikitosKey]

I really dig this plugin. I love attaching stickers to everything and everywhere. Before I used MAKE.md, I was using the default file explorer with the Iconize plugin. I also used Notion, and in both, I tagged almost all my files and folders with icons. In the emoji selection menu, there were rows of recently used icons in both apps, which made my life so much easier. I'd also love to be able to insert icons by typing them in.
