About improved UI and touchscreen...
Menus are a clever way to navigate thru params, but... the more level we have the harder is usability.
A real amp has a menu with one level (the knobs and switches).
Axefx has multiple level menu, since we can't have thousands of knobs! But each time we "navigate" into levels, we loose the "real amp interface".
Axefx has physical nav knobs: to reach Reverb Mix, we had to go Global Setup, scroll trhu second level menù and select Rev mix. To select amp type, we have to scroll...
A touchscreen helps a lot to lower "scroll". Each "button/area" of the touchscreen is a nav knob. Maybe all system menus could stay in one "setup page". Each amp type in a page can be select. No more need for physical navigation knobs. More space for "functional" knobs, or switches (or I/O).
