I really like the heatmap functionality provided by this extension, but I'd like to see it without all the extra info that shows up when the blame sidebar is open

So you'd want to see the heatmap visible all the time? Or just on a toggle -- like the normal blame, but without the extra info?

I think a toggle would be good. I'd probably leave it on all the time, but I could see others not wanting it.

[eamodio]

@dkniffin So you'd want to be able to toggle the heatmap by itself, but still have access to toggle the blame annotations too right? I ask because today you could configure the blame annotations to not have a message and just the heatmap (but of course then you can't turn on the messages without editing the config).

[dkniffin]

Ideally, yeah, that's how I'd like it. Removing the messages is a good workaround though.
