Great idea. You could right click on it, (or do the equivalent on an Apple), select "hide", and you would see it go "whoosh" into the Hidden folder right there on the screen. Or you could just click and drag it over to the hidden folder.In a perfect world yes is should... but people continually seek new things to complain about.
In the case of the MS-50 which actually has that option, the product cannot hold EVERY option and therefore that becomes the focus of complaints
As a Helix User.... I would love a simple "hide" feature. Once an amp or effect is hidden it won't appear in the day to day choices but can be accessed in it's own folder (aptly named "hidden") in case you wish to "unhide" it later. No computer required.
What if all the amps were put in some kind of logical order--- let's say from cleanest JC120 up to highest gain options? That might be helpful, too. then cab choices, for each amp you choose the cab choices would automatically be ordered from most likely to least likely. For example, if you choose a JMP head the first choice is a 4x12 with four vintage Celestions. If you choose a JC120 your first option is going to be a 2x12 open back cabinet.
