I'm missing this feature the most to speedup some statistics collection throughout the week, i.e. how long was I studying total
I was planning to add a checkbox in settings + tooltip text on hover for the timeblock. Adding text to the block itself sounded too complex and interruptive to me but that may be the better option.

@benjwu2 @ivan-lednev what are your opinions on hover tooltip vs. inline time?

Also what should be the duration format? Someone may want to have it like "50 minutes" or "30m" or "1hr15m" or "00:15" or "2'30''"

I'd say that should be another setting after the checkbox is checked

@bogdansalyp Personally, I would prefer inline time, as I'd like to be able to see the durations of all task blocks at a glance, without having to hover over each one to see their duration.

@benjwu2, can you share a screenshot or a drawing of what you have in mind?

Hi @ivan-lednev, here's an example:
