Basically the KPA is what it is, if you want to edit everything with an editor-software you have to buy a different gear.
Complaining about not having a full editor imho is a waste of time,... If there will be one it will be released by the company.
Just compare the three important digital guitar devices (KPA, Axe-FX, Line 6 Helix) and decide what's best for you. I never missed a KPA-editor, because there are a lot af advantages if you can edit a stand alone-device f.e. on stage.
Nothing prevents you from using an editor at home/in the studio and the front panel on stage, but I guess you don’t use RigManager either then?
