Hi!
I would welcome better error reporting or a debugging mode.
I'm reworking some old code made for before HTML5 and it's extremely frustrating having only silent errors or weird behavior.
The old "XML parsing failed" is a classic. The code is valid XML, but in one of the 1000+ lines of code, there is an Krpano error.
One character commenting would also be very welcome and at least ameliorate a bit of the debugging difficulties.
Rant over.
That said Krpano is still the only choice regarding pano work.
