nth team: 3rd, 4th, etc, team in mission like in redalert where there are friendlies you can't control, the scene designer should be able to specify colour of heart, for campaign I recommend teal.

Button: actor walks up to it and there is a 'push' option in pie menu, basically you attach the script to the specific button in the scene editor, Lua commands might be: GetPushed(), returns actor ID that pushed it, ie :

And an on push event.

Computer panel, ala Time splitters, created in Panel Editor and you can choose wether or not it pauses gameplay. Can be closed with the cross in corner. Possible out put are: live stream, shows specified area of game on a specified area, like a security camera, text, basically just text, gauge, different types i.e. round, straight and choose colour, and lastly: primitives, shapes, useful , for radars etc. Inputs would be: button, normal push button like submit on forums, check box, checked or not: can specify bitmaps for states, slider, slides, input, like the box which you type into in forums: can be restricted max length or not, and lastly lists, list of items that you can select, like the time zone selection on forums. Panels can have seperate scenes in, not scenes like levels but like a booting scene and a normal scene on your PC. All aspects of a panel and sub-scenes should be accessable with Lua, each scene has a script.

And a small request: inventory editor for scene editor, with editable sub inventories, ie Rocket>>Robot>>Gun, and it shows contents much like base building block selection box.

More teams could also enable 4 players mutliplayers !

we currently have 4 teams, team 0, 1, 2 and 3, unfortunately only teams 0 and 1 display team sides and health. actors on Team 0 and 1 both attack teams 2 and 3, we used it in our Tau mod to make photon grenades (shoots little bright balls everywhere that fly around and actors on both teams try to shoot them, we used team 2 so that its not team specific)

we also have the colors blue and I think yellow for teams 2 and 3, but they aren't used. I have no idea why, maybe data thought 4-way game-play was to much.

also for new custom things, I think that you should be able to save and load pre-sets to files, so that when you start you can auto-load presets right off. also, a basic lua editor/macroed editor, like triggers in starcraft/warcraft, that could be included in the area editor would be wonderful, but would require HUGE amounts of work and would probably be the last thing added (maybe even harder than internet/lan play)
