Improved Discord Functionality (Search options and Permissions)

I would like to suggest 3 different features that could improve discord's overall functionality. The first one is to add more search attributes to the search option . It already allows you to find messages that have links, embeds, videos, or images. I believe there should be an extra attribute for stickers, emoji's, users with a certain role, and messages that do not include certain text. Have a look at Image #1

Second is easier emoji search. Because the emoji picker can get very long, especially with nitro, it would be nice to search for specific servers that have a certain emote the same way you would search for a server using the QUICKSWITCHER (CTRL + K). With the quickswitcher, you can add a * before your search to find a specific server, and i think the same thing should be applied to the emoji picker, and possibly the sticker picker. Have a look at Image #2

Thirdly would be to add certain perms that allow/disable the use of stickers even if you have nitro. In some servers, its just not wanted, especially since custom stickers can get out of hand. i understand why it may not be a feature, but i think it would be nice nonetheless

IMAGE #1

(We can already search for link's embeds, file's, and etc. More options like mentioned above could come in handy)

IMAGE #2

We can already do this:

But it would be nice if we could do the same thing here:
