There is soon to be a new version of the OFP Mission Assistant.
The new version, 1.35 will include a weapons database that will allow the user to enter user made weapon names into the MA database. This will allow the user to easly create a description.ext for weapon selection with newly made weapons.
There is also improved support for multiplayer briefings,(East,West, Resistance,Civilian) Init.sqs wizard, and a Description.ext wizard.
1.30 is offically out right now, and supports Multiplayer briefings for east and west, and includes the Init.sqs wizard and descriptian.ext wizard but does not include the weapon database
