Time boxes configurable

During classic Lean Coffee sometimes I use to switch from a 5'+5'+5' timeboxes per topic to a pattern like 7'+5'+3'. I hope it would be an option. Thank you for this beautiful powerup.

Rather than clutter the issues, I'll comment here that I'd be happy with simply being able to set it to something other than 5 minutes, no pattern required. We used to always do 15 minute blocks in the long-long-ago before The Quarantimes.
