Very nice.
A few things that might be considered.
1 Get rid of the Properties side bar. I realise that most developing tools have this, but because there is very little information that is displayed - taking up so much of the screen is not really worth it. Options include double-clicking an object to display this information, or a floating window.
2 There is currently no real-time error checking. Is this an option.?
3 The level building error checking is not complete. This should check for start/end mission information, valid number of units present (at least one.!)
4 Small thing, can you display a progress bar for loading missions. Whilst it runs very smoothly on my PC, users with lower spec might notice a long delay before anything happens.
Thanks, and this is only after editing for 5 minutes.!
Oh, btw, if you want a user guide written for it, email me seperately with any layout specs etc and I'll be happy to have a go.
