I've always used this script that basically clears the deathnotice feed. The reason I do this is because of how I like my deathnotice feed displayed: minimal. When I first made a similar hud modification I used a font for the deathnotices that only had one character in it and it was a square. So your deathnotices would simply be red or blue squares and you could see the player counts without ever pressing tab. For example, each blue square represented one blue guy dead, etc. What I came to realize was that it's not just that you know a guy died, but also who it was that died. Then I thought of this idea, which is the next best thing.
What I did was crop out the left side of it so only the person that was killed is displayed. The reason it's not perfectly even is because you can't center justify the deathnotices as far as I know. I'm sure there are some hud developers out there that can make this look a lot prettier than it is.
This is the script I use to clear the feed inbetween pushes, etc. The script coupled with the hud modification allow for better pointing out of who just died in between spawn waves/pushes/etc.
alias +cleardn "hud_deathnotice_time 0"
alias -cleardn "hud_deathnotice_time 21"
TLDR; Minimal deathnotice feed mod + script that clears the feed in between spawn waves/pushes/etc. Minimizes the amount of times you have to press tab throughout the game.
