1. No prob! It's fun to see the game work its way from these eraly stages to the final game that'll be released in the months ahead (9 months, I beleive). Keep the feedback coming and we're bound to have a game that pleases as many players as possible! 
2b. This would probably work, or perhaps have an X button next to all filled slots..or something more intuitive than what's there now 
2c. They'll eventually be sortable by their weapon type (Mass Driver, Beam, and Missile), then sorted alphabetically (Lasers Mark I, Lasers Mark II, Phasers Mark I, Photons Mark I, ect).
3. Eventually the scrolling speed (when you mouse over an edge of the game window) will be an option that can be set by the player. For now we can speed it up for everyone, since alot of players are complaining about this.
