Would it be possible to choose by which field to sort observations (presently observations are sorted in reverse chronological order)? The other fields are Object Name, Session and Observing List?
This would be very handy for comparing a sequence of observations of the same object over time.
On a related note, it would be nice if we could "bring up" all observations for a given object in an observing list by via the observing list itself. Reviewing prior observation notes on an object in an observing list would be wonderful context for making the next observation.
