Well, if you browse through rigs using Browse you see 8 rigs at once in the display. That gives you a good overwiew and allows you to select a rig quickly.
Opposed to that browsing through performances using Type lets you see only 1 performance at a time. Selecting a performance is much slower, in particular if you select by name rather than number. My KPA has 75 performances stored. On stage I sometimes need to find one of these within seconds.
Usability could be improved sigificantly by letting us browse through performances in the same way as through rigs. Let the Type button select whether you're browsing through rigs or performances.
To me browsing through rigs in performance mode makes no sense at all unless I want to edit the performance. There is an 'Edit' soft button for that.
Thank you for spending your time, viabcroce.
