Allow the weapon box to remain visible during turns, and whilst scrolling around the map.
In most schemes we already know which weapons are available during turns, so this isn't really an important issue.
There are now however a large number of players playing the Rubberworm scheme "Kaos", it has its own league and community. During a game of Kaos players will collect many weapons from crates, and are able to use as many weapons as they like during their turn. With the inclusion of "real time worms" in 4.0, I feel this feature would be very useful for that too.
The problem is that players need to stop moving in order to view their weapons and this can ruin the flow of a turn. Whilst I recognise the skill in being able to quickly right click whilst jumping across the map, it would be far better if you could have the weapon box visible all the time.
This way you can view your weapons as you are navigating the map without having to stop and start, opening and closing the box. It would also be good to be able to scroll around the map when its not your turn, with the weapon box still visible. This allows you to scan the map at the same time as looking at your weapons, in order to plan the next turn.
Cant imagine this would be too hard to do, and it would be a real benefit for many schemes!
