Advice from Mariusz Gil: developers typically use maybe 30% of their editor's features; for remote EventStorming you must master every tool instead. Two reasons: (1) your toolset should be as small as possible (like a microservice) to avoid overwhelming non-technical participants; (2) fumbling for 10 minutes while 25 people wait is a huge waste. His go-to set is Miro + Zoom; ideally eliminate one if possible. Mastery also protects creativity — you can visualize anything (a relationship, a picture worth more than a paragraph) without breaking flow.
