I doubt this is possible for the current version of the client, but in 2.0 can we have the capability to re-order the party members in our list (Possibly by dragging the bars on the side around)? One of the slight annoyances as a healer is trying to remember which target is what priority for my cures. The main tank might be my F2 key one day, but F5 the next. This goes extra for jobs that may need extra care (the DoL/DoH needing stoneskin and esuna constantly during Hamlet for example), especially since the same person isn't always on the same job, so I can't rely on that.

I know there's ways around it (commit who's on what to memory at the start of the party, ask them mid-fight, etc.), but every little bit helps to keep the most pivotal role running smoothly.
