Asking for suggestions

Dear Developers,
As you can see I submitted a preliminary version of the demo app.
I had some problems with saving the configuration of numerical propagators, especially with building a force model and saving it in the DB for successive propagations of each satellite. I would like to avoid the user to reconfigure a forces' model every time a propagation has to be started, that's why I am trying to save this configuration in the DB.
For the moment, you can use Keplerian and TLE propagators, since they are very easy to use and to configure: I saved them with a simple String field in the DB, but I would need a more structured solution. Luc just gave me some suggestion, but I wanted to explain to all of you the reason of the current temporary approach.
Then, some features to update and edit existing objects still miss (Scenarios, Satellites and Ground Stations) and I am working on selecting from runtime the Events to be considered in propagation. Since they could change from one propagation to another I decided not to save them in DB.

For any type of suggestion, hint for editing, changing, improvements or highlighting, please let me know.

Thank you for your support,

My best ragards,

Roberta
