Noticing that lots of people (including myself) use emojis to help discover certain groups or layers in our sidebar. It will be so helpful to color code pages and layers on it tho.

Also a grouping method for pages (with folders will be great!!!, I find myself hacking my way to create groups on the pages using uppercase and emojis as well.

Photoshop, as an example, allows you to color code layers.

Finder, on mac, does the same with files allowing you to add a dot of color to files.
