Maintain labels to the left with horizontal scroll

When scrolling horizontally to the right, the labels disappear, and with many labels I have to keep scrolling all the way back to refresh in my memory what they are.

I've also come up with a "hack" to have two windows open, each with the same eventlog visualisation, leaving one where i can see the labels.

IMO This would be the single most MASSIVE UX improvement possible to this tool.
