Emojies as container is a great idea, however, I want to add more to this.
why not add an advance setting to choose whatever .png file the user want (with a set of dimension specified )
i have certain disability and the current scheme is hard on me because it take a lot of time for me to find the right container, I tried to change the color etc. but it didn't help, on other software which let me use custom images/colors it helps me a lot. I feel this is more an accessibility feature than cosmetic.
here is more related to this:
Emojis as Containers icon.
full color control (instead of just limited, why they decided on that!?).
custom .png files for the container icon (please add beside the button which select the .png file explanation of what resolution/file are supported).
folders to add Containers in to.
separators (like in Bookmark folders).
Search option (when you hold or right click on the New Tab button).
