What a great piece of software.!!!
I would like to suggest that Tonfotos add the ability to have multiple seperate libraries so that I could use one library for photos, and an additional (not - related) library for videos.
Other users might like seperate libraries for family, friends, work, etc…. This feature could also be applied to folders in the library.
This would greatly increase the functionality of the software.
I would add that the software should also be able to switch libraries in real time so only one Tonfotos has to be opened. Perhaps a selector to choose all libraries (or folders), or a specific library (or folder)?
