Importing observations from files and or cut-and-pasting them from an excel worksheet seems a bit awkward.  Two things might improve the process:

1) character spaces within the individual header items could be removed, or substituted with a "-"; e.g. Observation type -> Observation_type, Obs. point -> obsPoint, etc.  so that they do not get split into multiple columns when pasted into Excel; and

2) Have the column specifying the observation group be visible in the FEPest observations table and not just when pasted to a spreadsheet.
