My third, and last, suggestion is:
The tagging of pictures is extremely laborious and there's lots of clicking involved.
Ideally I would like to see a structured hierarchy and when the time comes to add keywords you could select the pictures and than dictate the keyword.
Eg.:
Structured keywords could be something like this: Oceania, Australia, Victoria, Melbourne, Eltham
Just by saying the word Eltham the software should than add all the rest of these keywords automatically.
Simple voice commands, such as: Next, Previous, etc. would improve workflow and efficiency dramatically .
Thanks for your time.
