Have used app for about a month for rapid capture of notes, to-do's, and setting of alarms from my menubar. Ran into some problems opening AquilaCalendarMB when I installed StickyBrain3. The developer has provided superlative customer support, answering e-mails quickly and working through the problem until solved (turned out to be a problem related to StickyBrain3, not AquilaCalendarMB). I'm very grateful for the excellent service.
