I am a little worried to have no message.
I hope you have been able to experiment the program.
The purpose of the demo version is to show the program's philosophy. I understand that you are disappointed not to be able to save the animations for the moment, but I work hard on the final version.

as suggested by wimvdb, I will start the TODO list.

TODO: Verify the existence of selected vertices for all functions which need selected vertices.
TODO: PAN function.
TODO: increase the wait time for reading OBJ files to 20s.
TODO: Delete files in the directory EXCHANGE? what method use?
TODO: Add the simulation parameters in each RECORDED IMPORT (.RIP)
TODO: Add the date in the name of each RECORDED IMPORT (.RIP)
TODO: Resetting the current simulation
TODO: Delete an item from the current simulation
TODO : Write animation files in various formats (PC2, MDD, ...)

Here is a preliminary list. The best is that every person who wants to add an item to this list, take it fully from its last state.
Personally, I also will take it fully by scratching completed items.

@Biscuits : you are right, the PAN function is really useful.

I certainly will do an update for the demo version during the next week.
