TL;DR: Allowing scripts to directly open the notecard UI for users would dramatically simplify configuration compared to dialogs, HUDs, or manual inventory editing.

One of the fallbacks in creating configurable systems for users is how the end user actually gets to configure things. Creating an elaborate dialog stream is complex and often becomes the work of an entire script. Creating a webpage and putting it on a prim is even more complex—and while it’s the prettiest option, few do it since it usually also requires attaching a HUD object.

The most typical solution right now is editing a notecard, which entails editing an object, switching to the correct prim’s Contents tab, opening the notecard, and remembering to save when done.

If a script could llLoadNotecard (similar to llLoadURL in a touch event) to open the editable version of a specific notecard in its inventory, we could offer an Edit button that conveniently opens the correct notecard for the user on demand. It could also open different notecards for different save states, which would likely be far easier for users to understand and manage.
