I don't understand your suggestion and what you think is missing.
Really not trying to argue or rant. I'm trying to offer suggestions on how you might improve things for many of your customers and trying to stay relevant to this thread.
Here's a real-life scenario -
I find a Rig that I like in the Rig Exchange. Let's say for this example I'd like to create copies for several different guitars and that I have Local Library folders for each guitar, each slightly modified to better match up with the guitar.
Using a "Save As" as I had described it, I would open the original Rig Exchange Rig, and decide it works for a Les Paul. I could then just click Save As, and from a popup select Local Library/Les Paul as a location, then save the rig as "Nice RE Deluxe". I have no need to be transported to the new copy that I stored in a different folder. I just continue editing the same original rig that should still be in the edit buffer, but now making changes for a Tele. When done I click "Save As" and from a popup I select Local Library/Tele as a location, then save the rig as "Re Deluxe for Tele". I'm lucky enough to have several guitars, so I continue this process for another 3 guitars.
And if I were trying to build a Performance in the same way, I would just have chosen "Performance XYZ/slot 3" or similar as a location, again naming it however I'd like.
So all I've had to do is find a rig, edit it in several ways, and elected to save it in multiple locations that I want, named as I want them. The interface is not sending me to other folders as I save changes and there is no confusion on what I've done. For instance, maybe I've made a new Performance called "RE Deluxe" with a slot for each guitar - LP, Tele, Strat, PRS, P90. Sounds pretty easy, no?
You also described using Word for comparison. This is exactly what someone would likely do. Just keeping the original document open, changing guitar names throughout the text, then using the normal Windows Save As to save a new document wherever they'd like under whatever doc name they'd like.
The same thing in the Kemper logic (and yes I know there could be several ways to get to the same end)
Open the rig from Rig Exchange
Save it to Local Library (not where I want it and still under the original rig name)
Now am I still on the RE rig, or my new Local Library copy? Not something here that everyone could easily know without checking.
Should I make a duplicate so as to hopefully not overwrite the new Local Library copy? So to be safe, I'll do this.
I forgot to rename the first one, so now I have "RE Deluxe" and "RE Deluxe copy", not where I want them and not named as I want them.
But since I'm now hopefully editing "RE Deluxe copy" I continue on making my mods for a Tele.
I hit Store and hope for the best.
This time I remember and rename "RE Deluxe" to "RE Deluxe LP". Do I need to store it? Don't really know for sure so I do it anyway.
I forgot to rename "RE Deluxe copy" so now I'm editing that for my PRS. Luckily, I remember not to just Store it, overwriting my Tele copy. So I duplicate it. Will it now be "RE Deluxe copy copy"? Will it be "RE Deluxe copy(2)"?
Once I figure all of this out, I finally have my 5 copies saved and named.
Now I have to go back and copy them to the set of folders I had created to keep things organized under Local Library.
Now I want a Performance, so I again need to copy/paste each to a slot in a performance. Do I need to Store again? It was a lot of work so I better. And I've been bitten once or twice when trying to change performance rigs so maybe I should just hit the Store button on the physical profiler just to be sure.
---------------------------------
Clearly there are several ways I could copy/paste/drag/rename and so on to get to that same end goal. But it's clear that this is the type of confusion that is often described by others as they try to do similar things.
And with Save As existing in pretty all other programs that save edits, that's a skill that pretty much everyone already understands. And even though the Kemper has work arounds, they cause confusion (obvious by the many threads on this), require more steps (more things to possibly go wrong), and requiring that the Kemper user know precisely the steps and the order to do those steps in.
I hope you pay attention to this. Obviously, it's your program to build as you please, and we can get by one way or the other. But there is a reason that some functionality, like copy/paste/open/save/save as are considered standards in most software and generally works the same everywhere.
