Sometimes I'd like to remove cookies and data just for a specific website, rather than all of my browser history, website settings, cache and cookies. The "forget about this site" function on Desktop does this.
On Android, deleting website data also clears your entire browsing history (as suggested to be changed here). This makes it especially annoying when you don't want it to be cleared, just the rest. It's annoying that the history is tied to website data, when you want the one thing cleared but not the other.
On Desktop, you can open your history and right click the site to "forget about this site". This will remove cookies, all history entries related to that domain, as well as basically anything the browser has stored about that domain (including bookmarks as far as I remember).
In addition to my above request, the "forget about this site" function should have options to choose from which things you'd like it to be deleted, rather than everything without a choice (on Desktop as well as Android, if implemented at any point).
