Hm, thinking about that; maybe it would be nice to allow opening hotspot without "perf.data", even if it exists - this could also be triggered by the empty file "" (or a new binary option).

Up to you, if you see a need for it I'm not going to oppose a patch for that.

I think if we extend #660 to start on several pages (for starters at least "recording" and "open") this issue is solved. Please have a look there any comment about a possible --startPage or how you'd name an option.
