Yes, we are long over due for an editor!
I've had 3 guitarists com & try my Kemper, they all loved it but brought other products because their was no editor.
I did a test with another brand vs Kemper. I had my mates "other product" with desktop editor & he had my kemper. The challenge was to see how quick & easy it was to get a clean, rhythm & lead sound programmed in & ready to go. I spent less than 1/2 an hour, no manual required. My mate was still going, cursing & swearing an hour later & fumbling through the manual before he gave up....unless you've used another product with a desktop editor & experienced how easy it is, you don't know what you're missing.
That said, I'm glad I've had to learn the front panel because if changes need to be made at a gig, it can be done. other products can be a pain.
At the very least they could tell us if there's one being developed or not. I have asked them & got a straight to the point "no comment" type of response.
