API ability to get "leading" events for query period

First I'd like to express again my thanks for such a wonderful and helpful project!

I've been using ActivityWatch for about two weeks now, and have also implemented a few very custom watchers for my own use cases. I'm currently running off of the latest tag, v0.8.0b7.

One thing I've noticed though that is a bit annoying to me is the Events and Query API behavior (and corresponding UI behavior) for long events that begin prior to the query period being cut off. For example, if I was AFK for a long amount of time until 30 minutes ago, and query for events in the last hour (or pull up the Timeline view in the UI for the last hour), I only see the "not-afk" event that started 30 minutes ago... and blank space leading up to it.

It seems to me like it would be really helpful if the events and query API endpoints had an option to return a "leading" event, if there's an event that started before the start of the query period but ended during the query period. I could also see this being represented in the timeline view with some sort of special icon or left border, indicating that the event began prior to the currently-viewed period.
