Changes I'd like to see in the Jungle Timers

So I've been playing a lot of jungle lately, and found myself instinctively, after every buff, putting the respawn time into chat. I knew that I didn't have to because of the built-in jungle timers, but as I played I found that it would be perfect to "take a guess" for a buff that you don't have vision of. That is, where there would be dashes indicating that you don't know, or if League thinks the camp is alive and puts the icon there accordingly, there would be a button that you can press if you think the neutral monster has just been killed. Whether it's a dragon that you see at 17 health before losing vision, or just a blue buff early game, I think this would be great. You can see your teammate's guesses right under the timer, and then add yours to the list. And secondly, I think that League should notify you if a dragon or baron has just spawned. I'm not sure if it should tell you off guesses or not, because that could lead to some trolling, but I do think that it would be better than realizing you could have just traded that tower mid lane for a dragon instead of defending it. Anyway, these are just some thoughts, and I'd love to hear your feedback.
