Basically there are two kinds of options, general "Application" options. These can be found under the menu:
File → extra → application configuration
There are as of now not many configurations, in general only debugging options (of Vide - not of vectrex).
The second set of options are regarding Vide.
These can be found at:
Tools → Configuation
All options are now bundled in one class and can as such be easily saved and loaded.
You can bundle all options to "sensible" names, like:
"Fastest emulation" "Default" "Added Timings" "Splines" etc
Upon start always the option "Default" is loaded! To save a configuration a Name must be entered (even the name "default")
