What would be useful is a popup modal window with progress bar and a busywait animation when loading or saving a character, to ensure you don't end up trying to get it to open two at once and get the data mixed up.

Progress bar might be incremented after processing Attributes, then Advantages, Disadvantages, skills, spells, equipment, whatever. Each section of the GCA file. Obviously some would take longer than others but at least you'd get a sense of progress ;)

The other approach, which I find amusingly accurate, is "This bar will animate randomly until the process is done" ;) I think anyone familiar with Microsoft OS's rather random "time to finish copying" estimates knows the feeling. I got to watch Windows 7 revise %age complete on something backwards and forwards for 15 minutes the other day.
