Might be cool to add the ability to highlight your bookmarks in different colours / bulk highlight your bookmarks.

I uncovered a little bit of a bug I can recreate with some trial and error (though it did happen the first time I was messing around with this functionality):

1. Highlight an area at a lower zoom level, and then a second highlight close by
2. Zoom out so the two highlights are overlapping
3. Zoom in, and a highlight bar that is permanent and follows you around will now be on the screen

It's pretty minor, refreshing removes it, so might not be a super big concern. Here's a mov of what it looks like:

Could also consider changing the order of the options around; for some reason I keep clearing all (impulse clicking the first option) when I mean to add to my existing highlights...something like:

• Add to existing highlights
• Set as only highlight
• Clear all highlights

[cmdcolin]

the highlight getting stuck was fixed in ca35e78 (needed to use array index to fully deduplicate the highlight keys)

[cmdcolin]

as long as we are talking about all the ways to get highlights, as there are many...getting highlights from e.g. an adapter like a bed could be useful...was done in jbrowse 1 with the concept of 'bookmarks' which were similar to highlights https://jbrowse.org/docs/url_strings.html#addbookmarks

[cmdcolin]

may try to deliver this type of highlight system as a 'plugin' that incorporates extension points to e.g. extend the lgv model and use #3663

from discussion at weekly ^^
