Yeah, some window managers seem to intercept the Alt key, so you'll have to fix that on your end, see OpenRA/OpenRA#12205.

You can force move by holding down 'Alt' while giving the move command.

You can't do that from the map editor but need to save the map unpacked, then navigate to the folder and edit the yaml rules yourself. You can look at the existing maps shipped with OpenRA for examples on how to disable buildings.

Yes, worms in our mod take a longer time to scare away/kill, but it is possible.

If you want to be sure you should look at the rules.ini file from the original game for values the original used.

You'll want to edit the values of SeedsResources on the ore mine actors which are usually in misc.yaml.

You likely have to open the port on your router (port forwarding).

They are waypoints used in the map script. You'll see the script using AtreidesEntry2.Location etc.

Yes, you'll also have to provide the path.
As to the bounds: You can simply change those values in the map.yaml file, there should be no issue in doing that.

Yes, that is possible using the utility (https://github.com/OpenRA/OpenRA/wiki/Utility).
If you use the AppImage on Linux you can do something like "./Dune-2000.AppImage --utility --resize-map MAPFILE WIDTH HEIGHT".

It will be for all players.

Hi. You need to use a newer engine version. Using this ModSDK release will fix your issue.

You can create a folder named "Support" in the game directory and move all files there.

The amount of slots is determined by the amount of spawnpoints set in the map. By setting more spawnpoints you will get more slots.

None of our streamers seems to have this issue. You can try if the "Use Hardware Cursors" setting helps here.
