I've had this rattling around in my brain for the last couple days, but I can't seem to come up with a smooth UX for this.
I'm building a stock graphing application. Included are around 300ish technical indicators, each with a number of user-configurable options. This will be presented in a popover (unless I can come up with a good reason for it to be elsewhere, modal, flip-side of the graph?).
The list of functions will obviously be searchable and perhaps filterable by category, but the twist is that users should be able to add more than one of the same indicator, configured independently, so I can't just use a table view with check boxes and disclosure circles.
The best thing I can come up with is a "currently enabled" list with an "add" button, but that seems limiting to me for some reason. Anyone better at UI than me got other ideas?
