(MaintC) Inventory favorites

[vir-linden]

Viewer work for inventory favorites. Related back-end work is tracked in https://github.com/secondlife/agent-inventory-service/issues/57

Basic concept is that any inventory item or category can be flagged as a favorite. UI will be provided to set or unset favorite status and to selectively view favorites when in inventory.

UX design TBD by steeltoe.

there is a lot of improvement that can be done around the inventory...

the search engine is very basic (keyword matching... no spellcheck, no suggestion, no extended vocabulary search)
For example:

• search keyword: shoes
• extended would be "shoe" and "shoes" (plural or singular)
• then "sneakers", "baskets", "high heels" "boots"

1 on 1 = 100% exact match
extended would evaluate the stats for being similar

I think there is a way "embeded" an "elastic search engine". (elastic search, like apache lucene, where made to make clever search and more than keyword exact match)

Thanks for the suggestions phenelle! I would be helpful to have these as a standalone feature request, either on the feedback.secondlife.com site, or as a feature request issue in the viewer repo.

Looks like this is part of Maint C but this is a first step towards proof of concept for metadata use, which then supports all things AI.
