Get into the feedback loop with them on the wish list and give them mockups for improvements that can't be easily explained.
The hardware interface drives the majority of actions available/allowed in the Editor.
Personally, I'd like to see the Editor available on our phones and tablets, in addition to the computers. I always have at least my phone with me IF I needed to change something when away from home. I try to set up my Per-Preset Performance Controls for the things I'm most likely to adjust, as a just-in-case.
I had the Boss GT-1000 before buying FM3.
The GT-1000 can be managed with its own mobile app via bluetooth (the device has bluetooth, so you can connect mobile to the GT-1000 via bluetooth without using any computer).
It's a powerful feature, but I was always going to the computer editor. A keyboard and a mouse are always faster, and the screen is always bigger.
In situations where I had no laptop, I always preferred to edit presets via the hardware unit, because it was easier and faster than the mobile. And screen of the unit is bigger also, it has more buttons, etc.
At the beginning I thought it was a great tool to have the editor in the mobile, but I realized that it was not useful to me.
Anyway, sure there are people who would like it and/or find it useful.
I hope FAS don't start working on mobile/tablet editor until they have improved a little bit the computer editors.
FM3Edit+AxeEdit should be updated with some improvements like browser, preset lists, shortcuts, notes, etc. There are a lot of small things to improve the workflow in these apps, as
@laxu said. There are a lot of wishes in this direction...
