Problem Statement

As work piles up the list of sessions gets longer and it becomes harder to find old sessions that you want to reference.

Proposed Solution

The sidebar in the desktop app could use two enhancements:

1. The ability to sort sessions by name.
2. The ability to organize sessions into groups.
