Could this plugin be able to change the lines that are thrown at a player's screen at once?
E.g. I use the Death Notes plugin and a lot of messages come in when somebody kills a lot of NPC's in a row.
It's like up to 7 lines that are on the screen simultaneously.
Could you add an option to change how many can be seen?
For me like 4 would be better to not fill the screen with these messages so much.
Thank you.

No, that is handled client side. You could slow them down perhaps, but you can't change how many lines show on your client.

Well, slowing down would make it worse, I guess.
Thank you for letting me know.
