I love having a workload threshold and being able to exclude some tasks from it. I put things like "chores" in the exclusion list because they don't really use mental energy the same way work does.

However, it would be really nice to be able to see the sum of non-workload tasks somewhere on a day view. Maybe it could be in the tooltip when you hover the yellow box up at the top of the task list column for a day. It could say something like "2h30m of workload threshold tasks planned, and 1h10m of other tasks, for 3h40m total"
