Description

Groupie makes a lot of requests to methods like getIndex(Item) which internally iterate through all the children of a group. In practice, this is rarely problematic, but it could become an issue with very deeply nested groups and items at the end of extremely long lists.

Contributor guide

Research direction
Profile the performance of getIndex(Item) in deeply nested groups and propose a caching or lookup structure to reduce iterations.
