The line thickness is matched to the Bezier curve logic so that lines don't overlap when there are multiple transmission events. This is how the arcs in https://next.nextstrain.org/ebola looks nicely...

Hmm... very interesting idea. However, I have to admit, I'd prefer it if the browser back button could just be a general purpose UI to go back to previous visualization...

This relates to a broader issue of how we calculate intervals for colors as well. Integer data may get non-integer coloring stops. Be nice to improve, but this is more...

Maybe we should always hide tip labels in scatterplot and clock views? They will very often be occluding.

Looks like IE11 still has ~1% market share (https://caniuse.com/usage-table). I can't test this on my computer, but if it's a simple fix it would be nice to do so. These...

I agree that this is annoying. Two thoughts: 1. We should definitely make sure that everything listed in `infoPanel.hover` is available in `infoPanel.click`. Easy to add "divergence" here. Were there...

>which will almost certainly be interpreted to mean that the ancestral state of the tree is HA1:198P and it has been lost many times. I'm afraid I don't agree here....

I definitely take your point on `--group-by week`, but there are some funny interactions here. In the current system we're often [mashing together geography and time](https://github.com/nextstrain/ncov/blob/master/nextstrain_profiles/nextstrain-gisaid/builds.yaml#L168) into our sampling categories,...

Thanks for the suggestion @AdmiralenOla. We implemented something similar to this idea for the "unrooted" layout. If you click on branches to zoom in [here](https://nextstrain.org/ncov/global?c=emerging_lineage&l=unrooted) you'll notice the sub-trees expand...

This is true. Divergent outgroup could affect clock.
