Do you have a roadmap for this mod up to version 1.0?
The obvious #1 thing is to make it as stable as possible. I've been trying to jump on bugs as soon as they come up, and the next release should fix some more exotic issues - mostly in (or caught by) the launcher.
#2 is trying to finalise the joystick support, which should cover issues as well as new features... I've bitten off an awful lot here, and now I need to figure out which of the more advanced protocols can actually be made to fit into the available space / logic. At first glance they seem to rely on very fast polling; ironic since I've spent so much effort slowing the game down.

I'm hoping we can have the cake and eat it too, but that's all I can say for now.
I'll likely sneak in some other minor improvements, but in terms of other major things which
might happen before 1.0 - the two things I'm thinking about are a combat difficulty setting, and localisation. Localisation is pretty huge though, and there's different possibilities for how it might work on several fronts, so I'm not 100% sure.
There's other things I'll be looking into post-1.0, but I don't want to make any promises - some may end up being beyond the time I have available. I don't have a particular timeline; I'd like to be out of beta within the next month or so though, but we'll see how that goes.
Can i suggest something? The savegame editor needs to be able to change the number of kills and number of sorties too. I'm saying this because when we finish the last mission those kills/ last sortie / medals are never counted, and when you transfer for the next campaign its almost like that last mission never happened. I'm using the old DOS tool called WCSAV, but wondering if you have any plans to expand on your savegame editor.
I can definitely add the ability to alter those; it's also an interesting point though that the results of the final mission are never saved... I honestly hadn't really given that any thought, and now I'm wondering if there's something which can be done about it. I'm not sure about the details or viability, but I'll be looking into it.
